Water, Hydrogen Bonds, and the Hydrologic Cycle
•
12 likes•6,982 views
Water is made up of hydrogen and oxygen atoms that are covalently bonded together into polar molecules. The polarity of water molecules allows them to form hydrogen bonds with nearby water molecules, giving water its unique properties. Hydrogen bonding is responsible for water's high boiling point, its ability to absorb large amounts of heat, and why ice floats on liquid water. The hydrologic cycle describes the continuous movement of water on, above, and below the surface of Earth, including processes such as evaporation, transpiration, condensation, precipitation, and runoff.

Water Cycle Powerpoint
The document summarizes the water cycle, which is driven by energy from the sun. Water is constantly being cycled through evaporation, condensation, and precipitation between the atmosphere, ocean, and land. Evaporated water rises into the atmosphere, cools and condenses to form clouds, then falls back to earth as precipitation, with some absorbed into groundwater and running into streams and rivers as runoff, completing the cycle.
Ppt Nutrient Cycles
The carbon cycle involves carbon dioxide being absorbed by plants through photosynthesis and converted into sugars, which are then consumed by animals through respiration and released again as carbon dioxide, completing the cycle. The nitrogen cycle transforms nitrogen between its gas and solid forms via nitrogen-
Carbohydrate metabolism and Glycolysis
This document summarizes carbohydrate metabolism and the glycolysis pathway. It discusses how carbohydrates are the major source of energy for cells and are synthesized through photosynthesis. Glycolysis is defined as the breakdown of glucose to pyruvate or lactate with ATP production. The key steps of glycolysis include an energy investment phase, splitting phase, and energy generation phase where ATP is synthesized. Glycolysis is a central and universal pathway that is important for energy production in tissues like the brain and red blood cells.
Biology Unit 1 Notes: Metabolism, Energy & Homeostasis
Homeostasis refers to maintaining internal stability and balance in response to changes inside or around the body. Metabolism and two key reactions, hydrolysis and dehydration synthesis, allow cells to break down and build molecules to transfer energy and matter. These reactions involve the addition or removal of water and are used to release or store energy in molecules like ATP and ADP as cells need energy to perform work.

Lipid catabolism (fatty acid oxidation)
1) Fatty acids undergo beta-oxidation in the mitochondria to break them down into acetyl-CoA units, releasing energy.
2) Beta-oxidation involves a four-step cycle that removes two-carbon acetyl-CoA units from the fatty acid.
3) The complete breakdown of a fatty acid like stearic acid yields 9 acetyl-CoA molecules which enter the citric acid cycle, producing a total of 146 ATP molecules through electron transport chain reactions.
Metabolism of Amino Acids
1) Amino acids from dietary proteins and cellular protein turnover enter an amino acid pool in the body. Glutamate and glutamine make up about 50% of this pool.
2) Amino acids are used to generate energy, synthesize proteins, and produce other nitrogenous compounds. They undergo transamination and deamination, with the amino groups being converted to ammonia.
3) Ammonia is disposed of through the urea cycle in mammals, where it is combined with carbon dioxide to form urea, which is excreted in urine. Disorders of the urea cycle can cause hyperammonemia and neurological issues.
Chloroplast
Chloroplasts are organelles found in plant cells that contain chlorophyll, which allows them to carry out photosynthesis. Chloroplasts have an inner and outer membrane, as well as internal structures called thylakoids that are stacked to form grana. Within the chloroplast is the stroma, which contains enzymes and DNA, allowing the chloroplast to divide itself. Chloroplasts are able to convert sunlight into chemical energy through photosynthesis.

Isomerases
Isomerases are enzymes that catalyze the rearrangement of molecules between isomeric forms. They convert a molecule from one isomer to another by breaking and forming bonds in an intramolecular reaction. Isomerases are classified into subclasses based on the type of isomerism they catalyze, such as racemases/epimerases which invert stereochemistry, cis-trans isomerases which change bond geometry, and intramolecular oxidoreductases, transferases, and lyases. Isomerases play important roles in metabolism, and deficiencies in certain isomerases can cause human diseases. They also have industrial applications such as in sugar manufacturing.
Glycolysis
Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process. It is an ancient and nearly universal pathway that occurs in the cytosol of cells. Glycolysis consists of two phases - the preparatory phase in which ATP is consumed to modify glucose, and the payoff phase in which net ATP is produced. Key steps include phosphorylation of glucose, isomerization to fructose, and cleavage and rearrangement to two trioses. This yields two pyruvate molecules, two ATP, and two NADH from each glucose. Glycolysis is highly regulated and crucial for energy production in most organisms.
Carbohydrate structure
This document discusses carbohydrate chemistry. It defines carbohydrates as organic molecules found in nature that are made up of carbon, hydrogen, and oxygen. Carbohydrates are classified based on their structure into monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides include important hexoses like glucose and fructose. Carbohydrates exhibit properties like optical activity and stereoisomerism due to asymmetric carbon atoms. Key topics covered include glycosidic linkages, reducing sugars, ring structure forms (pyranose and furanose), and epimers. Physiologically important monosaccharides and derived sugars are also mentioned.
Enzymes
Enzymes are biological catalysts that increase the rate of chemical reactions without being used up. They are proteins folded into complex shapes with active sites that substrates fit into like locks and keys. Enzymes are usually named for their substrates with the ending "-ase", such as lipase and proteases. Enzymes have five key characteristics: they are always proteins, are specific to reactions, can be reused, are denatured at 50°C, and have optimal pH levels. They are made inside cells and can work inside or outside of cells to speed chemical reactions. Enzymes are widely used in industry due to their ability to work at low temperatures and only be needed in small amounts.
Carbohydrate metabolism, part 1
This document discusses intermediary carbohydrate metabolism, specifically glycolysis. It begins with an introduction to glycolysis, noting that it is the degradation of glucose into pyruvate through a series of 10 enzyme-catalyzed reactions. These reactions can occur aerobically, producing pyruvate, or anaerobically, producing lactate. The document then delves into the specific reactions, enzymes, and intermediates involved in both the preparatory and payoff phases of glycolysis. It also discusses the importance of 2,3-bisphosphoglycerate in red blood cells for regulating oxygen release from hemoglobin.
Digestion and absorption of lipids
Lipids are digested and absorbed through a multi-step process. Dietary lipids are broken down by lingual and gastric lipases in the mouth and stomach. In the small intestine, pancreatic lipase works with bile salts to emulsify and further digest triglycerides into fatty acids and monoacylglycerols. These products form micelles that enable absorption by enterocytes. Within enterocytes, fatty acids and monoacylglycerols are re-esterified into triglycerides and combined with cholesterol to form chylomicrons, which transport the absorbed lipids into the lymphatic system and bloodstream. Chylomicrons are then broken down by lipoprotein lipase in capillary beds

Protein metabolism
1. Protein metabolism involves the breakdown of amino acids into ammonia and carbon skeletons, and the reuse of these components for new protein synthesis or energy production. Amino acids undergo transamination, deamination, and are metabolized through the urea cycle to dispose of ammonia.
2. The urea cycle is a series of chemical reactions that converts ammonia into urea for excretion. It occurs primarily in the liver and involves five enzymatic steps to incorporate ammonia and carbon into the relatively non-toxic urea molecule.
3. Defects in protein metabolism can cause inborn errors such as phenylketonuria, maple syrup urine disease, and defects in the urea cycle, which
2.2 water
Water is essential for life due to its unique properties arising from hydrogen bonding between polar water molecules. Water's polarity allows it to dissolve many other polar substances and ions, acting as a universal solvent and transport medium in organisms. Water's high specific heat capacity and heat of vaporization enable important thermal regulation processes. In blood, glucose, amino acids, and ions are carried in the plasma due to their polarity, while fats and cholesterol require transport in lipoprotein complexes due to their nonpolar nature. Oxygen is only slightly soluble in water alone, and is mainly transported bound to hemoglobin in red blood cells. The document discusses these topics through examples and comparisons to methane.
Water and its importance
All living things need water to survive. The human body is composed of 70% water and plants are 95% water. Water is essential for agriculture, industry, personal use, transportation, climate regulation and providing habitat. It exists in three states - liquid, solid, and gas. The water cycle involves evaporation, condensation, and precipitation through which water is recycled through the atmosphere and environment. Water conservation methods include fixing leaks, limiting water usage, rainwater harvesting, and preventing pollution to safeguard this vital resource.

In humans, non-essential amino acids are synthesized from intermediates in major metabolic pathways such as the Citric Acid Cycle.
Cellular respiration updated
Cellular respiration involves three main stages - glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis breaks down glucose in the cytoplasm, producing pyruvate. Pyruvate then enters the mitochondria and is converted to acetyl-CoA to feed into the Krebs cycle, where more ATP is generated. In the electron transport chain, electrons are passed through protein complexes in the mitochondrial membrane, establishing a proton gradient used to power ATP synthase and produce large amounts of ATP through chemiosmosis. The overall process is the reverse of photosynthesis and harvests energy from food to produce ATP for cellular work.
Metabolism of carbohydrate
This document summarizes carbohydrate metabolism pathways. It discusses glycolysis, which breaks down glucose to pyruvate or lactate with ATP production in the cytoplasm. Pyruvate is further oxidized to acetyl-CoA in mitochondria to enter the TCA cycle. Glycolysis is regulated by hormones like insulin and glucagon. It provides energy and carbon skeletons for various biosynthetic pathways. The document also explains aerobic versus anaerobic glycolysis and the fate of pyruvate under different conditions.
Denaturation of proteins
This document discusses protein denaturation, which is defined as any change that alters a protein's unique 3D structure without breaking peptide bonds. Denaturation can be caused by heat, acids, bases, detergents, or other physical and chemical factors. It disrupts secondary, tertiary, and quaternary protein structures but not the primary amino acid sequence. Denatured proteins lose biological activity and may aggregate. In some cases denaturation can be reversed but often it is permanent.

The Water cycle by "TAPLOR"
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from bodies of water and soil into the air, where it condenses to form clouds. Water then falls back to the Earth as precipitation, where some soaks into the ground and some flows across the land and into streams, rivers, lakes, and oceans, completing the cycle. Water is always changing states between liquid, gas and solid as it moves through the cycle.
Hydrologic Cycle
Water is essential for life and the hydrologic cycle distributes it around the planet. The cycle involves evaporation, transpiration, condensation, precipitation, collection as runoff or infiltration into groundwater, and storage in oceans, glaciers, and ice caps. Climate is influenced by the hydrologic cycle as warm air holds more water vapor and rising air cools, causing precipitation. Changes to the cycle, such as intensification due to climate change, can produce more extreme flooding and drought.

Glacial transportation and deposition
This document discusses different types of glacial landforms formed by the deposition of debris (moraine) transported and deposited by glaciers. It describes erratics as large rocks transported far from their source, moraines as ridges of glacial debris including terminal, lateral, and recessional moraines, and drumlins as streamlined hills that indicate the direction of past ice flow. Drumlins are proposed to form through subglacial deformation as the glacier becomes overloaded with debris and moulds it into characteristic elongated shapes aligned with ice movement.
Pyramids
This document summarizes different types of ecological pyramids including pyramids of numbers, biomass, and productivity. It explains that pyramids of numbers show the relative population sizes at each trophic level, while pyramids of biomass show the total mass of organisms. Pyramids of productivity represent the flow of energy through trophic levels, which typically decreases at each level as only 10% of energy is transferred. Examples are given of each type of pyramid along with their advantages and disadvantages. Key concepts around species, populations, communities, niches, habitats, and ecosystems are also defined. Different biotic interactions like competition, predation, symbiosis, commensalism and parasitism are briefly explained
Ecological pyramids
Each level in an ecological pyramid represents a level of producers or consumers in a food chain, with less available energy at each ascending level. Producers such as plants are at the bottom, while top carnivores are at the top with the least biomass due to the loss of energy at each transfer between trophic levels.
Ecological cycles
The document discusses several biogeochemical cycles and how human activities impact them. It provides figures and descriptions of the water, carbon, nitrogen, phosphorus, and sulfur cycles. For each cycle, it summarizes how human activities like burning fossil fuels, agriculture, deforestation, and industrial processes alter the natural cycling of these essential elements. It concludes by briefly introducing the Gaia hypothesis that life influences or controls Earth's climate and other environmental processes.
Water cycle ppt
The document discusses the water cycle through a table of contents that explains the key parts of the cycle: evaporation and transpiration caused by heat from the sun, condensation which occurs when water vapor cools, precipitation when water becomes too heavy for the atmosphere, and how the cycle recycles water on Earth. It includes diagrams and a song to help explain the process of water traveling through the stages of the cycle from liquid to vapor and back again.
Ecological pyramids
Ecological pyramids graphically represent trophic structure in ecosystems. There are three main types: numbers pyramids show individuals per trophic level; biomass pyramids show mass per level; and productivity pyramids show energy flow between levels. Numbers pyramids typically have a broad base of producers and narrow top of apex predators. Biomass pyramids can be inverted in aquatic systems depending on species longevity. Productivity pyramids show only 10% of energy is transferred between trophic levels. Pollutants can biomagnify up food chains, becoming more concentrated and potentially toxic at higher levels.
Colon cancer
Colon cancer typically begins as a noncancerous polyp in the lining of the colon or rectum and can become cancerous over time. Risk factors include age, family history, diet high in red meat and saturated fats, obesity, smoking, and alcohol use. Screening is important, as early detection improves outcomes - average risk adults should be screened beginning at age 50. Colon cancer is staged based on how far it has spread, with treatment options including surgery, chemotherapy, and radiation depending on the stage. While early stage cancers can often be cured with surgery alone, advanced cancers are difficult to treat and the goals shift to slowing growth and managing symptoms.
Phosphorous cycle
The phosphorus cycle involves the movement of phosphorus through the environment and living organisms. Phosphorus moves slowly through soils and oceans but cycles more quickly through ecosystems as it is absorbed by plants and animals and returned to soils through decomposition. Humans have significantly impacted the phosphorus cycle through mining phosphorus ores, use of phosphorus fertilizers, and transporting phosphorus-containing food and waste. This risks over-enrichment of waters with phosphorus from runoff and effluent, contributing to accelerated eutrophication of water bodies.
Colorectal Cancer
This document discusses colorectal cancer. Some key points:
- Colorectal cancer is the second most common cause of cancer deaths in North America. It affects the colon and rectum.
- Risk factors include family history, age over 50, inflammatory bowel disease, poor diet, smoking, and diabetes. Genetic changes like mutations in APC and DNA repair genes contribute to colorectal cancer development.

Phosphorus cycle
Phosphorus was discovered in 1669 by Hennig Brand in Germany. It exists naturally as phosphate rocks and plays an essential role in biological processes. In the phosphorus cycle, phosphate rocks weather and release phosphorus into water. Autotrophs then absorb phosphorus from water or soil, which is consumed by heterotrophs. Phosphorus leaves bodies and decomposers return it to soil or water to be absorbed again by plants, completing the cycle.
Oxygen cycle
Oxygen cycles through the biosphere, atmosphere, hydrosphere, and lithosphere. Plants produce oxygen through photosynthesis, using carbon dioxide, water and sunlight to produce sugars and release oxygen into the atmosphere. Animals and other organisms use oxygen for respiration, breaking down sugars and food and releasing carbon dioxide and water. The carbon dioxide is then used by plants in photosynthesis, continuing the cycle.

Water lecture
Water is essential for life and covers most of the Earth's surface. It exists in three states - liquid, solid (ice), and gas (water vapor). Water is a polar molecule made of one oxygen atom bonded to two hydrogen atoms. Its unique properties, like being a universal solvent and having a high heat capacity, help regulate the Earth's climate and temperature. Water is distributed throughout the universe and is critical for habitability in Earth's "Goldilocks zone" where its three states can exist simultaneously.
Properties of water
Water has unique properties that allow life to exist on Earth. It has a chemical formula of H2O and forms hydrogen bonds between molecules. These bonds give water high surface tension, heat capacity, and ability to dissolve many substances. Water's polarity and hydrogen bonding allow it to dissolve more substances than any other liquid. Its high heat capacity and heat of vaporization help regulate temperatures on Earth. Water's density peaks at 4°C, causing ice to float, which protects aquatic life below freezing surfaces. These unusual properties are crucial for life.
Chemical composition of water by Group 2
Water is the most abundant compound on Earth, covering 70% of the planet's surface. It exists naturally as a liquid, solid (ice), and gas (water vapor) and is essential for life. Water has unique physical properties including being transparent, colorless, virtually odorless and tasteless as a liquid. It has a high heat capacity and heat of vaporization due to extensive hydrogen bonding between molecules. These properties allow water to moderate the Earth's climate. Water plays a vital role in all living organisms, making up 55-78% of the human body.

Water is essential for life and has unique properties that make it suitable for life. It exists in nature as a liquid, solid, and gas and has an anomalous property of becoming less dense when frozen. Water's polarity and ability to form hydrogen bonds give it high surface tension, heat capacity, and ability to dissolve many substances, making it a universal solvent. These properties allow water to moderate climate, support biological processes in cells, and drive the water cycle which is crucial for life on Earth.
Water: Structure and Properties
Water exists in three states and has unique properties due to its molecular structure and ability to form hydrogen bonds. As a polar molecule, water can form up to four hydrogen bonds with neighboring molecules, giving liquid water high cohesion and surface tension. This also accounts for water's unusually high melting and boiling points compared to similar compounds. The hydrogen bonding in ice locks molecules into a rigid crystalline structure that floats, allowing aquatic life to survive under frozen ponds and lakes.
Properties of water and its global distribution
The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles), with 97.5% being salt water and 2.5% being fresh water. Of the fresh water, only 0.3% is in liquid form on the surface. In addition, the lower mantle of inner earth may hold as much as 5 times more water than all surface water combined (all oceans, all lakes, all rivers).

Tropical Rainforests
Tropical rainforests have an average temperature between 20-35°C and receive heavy rainfall between 200-400cm annually. Over 50% of all life exists in these forests, which only take up 2% of the earth's surface. The forests grow on acidic, nutrient-poor soils and have a structure with multiple layers - a forest floor, understory, and canopy or overstory. Fig trees are crucial to the forests as they provide a food source for birds and mammals through their fruits, and army ants that travel across the forest floor in swarms are followed by birds eating the debris left behind.
Henri Becquerel
Henri Becquerel discovered radioactivity in 1896 almost by accident. While experimenting with uranium salts and their effect on photographic plates, he discovered that the plates were exposed even when not in direct sunlight, showing that uranium emitted radiation without an external energy source. This led to his discovery of radioactivity, the spontaneous emission of radiation by a material without external energy. For this discovery, which helped establish the field of nuclear physics, Becquerel shared the 1903 Nobel Prize in Physics with the Curies.
Texture
This document defines and discusses the concept of texture. It provides several definitions of texture relating to woven fabrics, the structure of materials, and the visual or tactile surface characteristics of something. It then analyzes the texture present in several works of art, including sculptures, paintings, and cloth, noting how texture adds dimension, depth, structure or roughness to depictions of mountains, water, grass or other surfaces.
Josef Albers
Josef Albers was a German artist born in 1888. He studied to become a teacher in Germany from 1905 to 1908 and taught primary schools from 1908 to 1913. After further art education, he became an art teacher. In 1950, he became head of the Department of Design at Yale University School of Art, holding that position until 1958 when he became a visiting professor until 1960. Some of his notable artworks include Black Circle from 1933 and Study for Homage to the Square from 1954.
Social Darwinism in Things Fall Apart
Okonkwo was a member of the Igbo clan in Nigeria who struggled to adapt to changes brought by colonizers and missionaries. When Okonkwo returned to his village, he found that his clan had failed to resist the colonizers' influence and adopt their ways, leading to the clan's demise. While Okonkwo had inherent flaws like his inability to adapt, circumstances like his absence from the village and the clan's initial dismissal of the colonizers also contributed to its downfall.
The Neshaminy Creek
The students collected macroinvertebrates from three sites along the Neshaminy Creek to determine the water quality. They found three types of macroinvertebrates: damselflies, caddisflies, and mayflies. Each of these are sensitive to pollution and their presence indicates good water quality in the creek. The students identified the macroinvertebrates using information from the Stroud Water Research Center.
The Sounds of The Night Thoreau Spent in Jail
This document provides summaries of musical pieces featured in a play about Henry David Thoreau spending a night in jail. It includes 4 summaries that describe the mood, tone, and progression of the music and how it corresponds to events in each scene. The music ranges from upbeat to gloomy and tense, mirroring interactions between characters and increasing tension throughout scenes.
The French and Indian War
The document discusses the origins and key events of the French and Indian War between the French and English in North America from the 1750s to the 1760s. It began as tensions rose between the French and English over territorial expansion in the Ohio Valley. One of the early battles was led by a young George Washington against the French at Fort Necessity. The war then escalated and involved the governments of France and Britain directly. Britain eventually gained control over much of North America after capturing Quebec in 1759. This shifted the balance of power but also increased tensions between the British and American colonists over control of the newly acquired western lands.
Population Decline in Russia
Russia has experienced a population decline since 1992 due to factors such as high abortion rates, decreasing fertility, poverty, and heavy alcohol consumption, with over 225 abortions per 100 births often performed without proper safety and leaving women unable to have children in the future, and the average Russian consuming more alcohol than is considered healthy according to the WHO.
Nuclear Proliferation
The document discusses different types of nuclear weapons such as fission and fusion bombs. It describes the gun and implosion methods used for early fission bombs and the Teller-Ulam design commonly used for thermonuclear weapons. The effects of a nuclear explosion are outlined as blast, thermal radiation, ionizing radiation, and residual radiation. Details are provided on nuclear testing conducted by various countries and images are shown from early tests. Nuclear arms control treaties like the Limited Test Ban Treaty, Nuclear Non-Proliferation Treaty, and Comprehensive Nuclear Test Ban Treaty are summarized.
Aluminum Group
The document discusses the aluminum group of elements, which includes boron, aluminum, gallium, indium, thallium, and ununtrium. Most of the elements in the group are soft metals found naturally as compounds rather than in elemental form. Boron and aluminum are discussed in more detail, including their discovery dates, common uses, thermal properties, and isotopes.
Environmental Racism
Environmental racism refers to decisions that restrict certain groups to polluted environments based on race. It has a history dating back to the establishment of environmental justice and the disparate impact standard in the 1970s. While laws like the Civil Rights Act prohibit discrimination, some argue that loose interpretations of environmental laws can give agencies too much power and prevent economic growth in low-income and minority communities. For example, a $700 million plant in Louisiana agreed to hire locally and donate to schools but was blocked by protests over its location in a predominantly black area. Many state and business groups oppose expansive definitions of environmental racism.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
