Metabolism final
Drug metabolism involves the chemical modification of drugs inside the body through enzymatic reactions. There are two main phases - in Phase I, functional groups are introduced onto the drug molecule through reactions like oxidation, reduction and hydrolysis, making the drug more polar and able to be eliminated. In Phase II, polar groups are conjugated onto the drug, like glucuronidation or sulfation, which allows the drug to be more readily excreted from the body. The major sites of drug metabolism are the liver, small intestine and kidneys, and it occurs through cytochrome P450 enzymes in the endoplasmic reticulum and cytosol of cells.
Metabolism II
The document discusses various Phase II biotransformation reactions. It describes conjugation reactions like conjugation with glucuronic acid, sulphate moieties, alpha amino acids, and glutathione. Conjugation with glucuronic acid is the most common reaction where glucuronic acid is attached to form glucuronides. Conjugation with sulphate occurs less frequently. Amino acid conjugation forms amide bonds between carboxylic acids and amino acids like glycine. These conjugation reactions make compounds more polar and water soluble for excretion.

These macromolecules are essential components of living organisms.
Biotransformation
Biotransformation refers to the chemical alteration of substances within living organisms, typically involving enzymatic reactions. These reactions make compounds more water-soluble so they can be more easily excreted from the body. Biotransformation occurs in three phases - Phase I involves oxidation, reduction, and hydrolysis reactions; Phase II involves conjugating reactions like glucuronidation and sulfation; Phase III involves transport of conjugated compounds out of cells and organs. The liver is a major site of biotransformation, with cytochrome P450 enzymes and conjugating enzymes playing important roles in Phase I and Phase II reactions. Biotransformation is vital for the metabolism of drugs and other xenobiotics in the body.

Carbohydrates are an important class of organic compounds that serve many functions in living organisms. They can be classified in several ways, including by their solubility, how they break down during hydrolysis, and their structure. The key types are monosaccharides (simple sugars), disaccharides (two joined monosaccharides), oligosaccharides (three to ten joined monosaccharides), and polysaccharides (long chains of monosaccharides). Monosaccharides can take cyclic or acyclic forms and exist as structural isomers called anomers that differ in configuration at the anomeric carbon. Some monosaccharides undergo mutarotation in aqueous solution as they interchange between anomeric forms.

The document discusses carbohydrates and provides definitions and classifications. It defines carbohydrates as polyhydroxy aldehydes or ketones that can be hydrolyzed into monosaccharides. Carbohydrates are classified based on the number of monosaccharide units - monosaccharides contain one unit, disaccharides two units. Common sources of carbohydrates are discussed including grains, fruits, vegetables, dairy and sweets. Digestion and absorption of carbohydrates is also explained.
Carbohydrate presentation by KK Sahu sir
Carbohydrates are the important organic compounds of the cell, which are the main source of energy of body.
They consist of carbon, hydrogen and oxygen which are found in the ratio of 1:2:1.
General formula of the carbohydrate is CnH2n or (CH2O)n chemically.
Carbohydrate are the aldehyde or ketone derivatives of the polyhydric alcohols.

Carbohydrates are aldehyde or ketone compounds that serve multiple roles in life. They store and provide energy through starches like glycogen, make up structural elements like cellulose in plants, and form the backbone of nucleic acids DNA and RNA. Carbohydrates exist as monomers, dimers, and polymers. Glucose is the most abundant monosaccharide and forms cyclic structures in solution. It links to other sugars through glycosidic bonds to create important disaccharides like sucrose and polysaccharides for energy storage.
Quantitative estimation of carbohydrates Likhith K
Carbohydrates are one of the three macronutrients in the human diet, along with protein and fat. These molecules contain carbon, hydrogen, and oxygen atoms. Carbohydrates play an important role in the human body. They act as an energy source, help control blood glucose and insulin metabolism, participate in cholesterol and triglyceride metabolism, and help with fermentation. The digestive tract begins to break down carbohydrates into glucose, which is used for energy, upon consumption. Any extra glucose in the bloodstream is stored in the liver and muscle tissue until further energy is needed. Carbohydrates is an umbrella term that encompasses sugar, fruits, vegetables, fibers, and legumes. While there are numerous divisions of carbohydrates, the human diet benefits mostly from a certain subset.
05 macromolecules
1. Carbon is the backbone of biological molecules in living organisms and can form single, double, triple, or quadruple bonds.
2. Hydrocarbons like methane, ethane and ethene are molecules made of only carbon and hydrogen. Lipids, which do not form polymers, include fats and phospholipids.
3. Carbohydrates, proteins, nucleic acids and lipids are the four major classes of macromolecules that make up living things and carry out essential functions.
Carbohydrrates lecture
The document discusses carbohydrates, which are a major source of energy composed of carbon, hydrogen, and oxygen. They include monosaccharides (simple sugars), disaccharides (two monosaccharides joined), oligosaccharides (3-10 monosaccharides), and polysaccharides (long chains of monosaccharides). Important monosaccharides include glucose, fructose, and galactose. Disaccharides formed from two monosaccharides include maltose, lactose, and sucrose. Polysaccharides are polymers of monosaccharides and include starch, glycogen, and cellulose. Carbohydrates have important biomedical roles as energy sources and structural components in the body.

SUBSTRATE LEVEL PHOSPHORYLATION IN GLYCOLYSIS
This document discusses substrate level phosphorylation in glycolysis. Glycolysis is the process by which glucose is broken down into pyruvate, producing a net yield of 2 ATP molecules per glucose through substrate level phosphorylation at two steps. In step 7, 1,3-bisphosphoglycerate is converted to 3-phosphoglycerate with the generation of ATP. In step 10, phosphoenolpyruvate is converted to pyruvate with another ATP generated. These substrate level phosphorylation steps contribute significantly to ATP production in glycolysis, especially under anaerobic conditions.
Overview of anaerobic respiration and factors affecting respiration & chemios...
The document discusses anaerobic respiration which occurs without oxygen using inorganic molecules like nitrates as electron acceptors, yielding less ATP than aerobic respiration. It also covers factors like temperature, oxygen levels, and chemicals that affect the rate of respiration. Finally, it explains chemiosmotic theory proposed by Peter Mitchell which describes how electron transport and ATP synthesis are coupled by a proton gradient across the inner mitochondrial membrane.
Regulation of glycolysis and Cyanide resistance respiration
The document summarizes the regulation of glycolysis and cyanide resistant respiration. There are three major control points in glycolysis - hexokinase, phosphofructokinase, and pyruvate kinase. Cyanide resistant respiration occurs in some plant mitochondria and allows respiration to continue in the presence of cyanide through the use of an alternative oxidase enzyme. This pathway produces heat, aids in fruit ripening, and helps with osmoregulation.
Pentose Phosphate Pathway and its application
The document summarizes the pentose phosphate pathway, including:
1) It is a metabolic pathway parallel to glycolysis that generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-phosphate.
2) It has two phases - an oxidative phase that generates NADPH and a non-oxidative phase that synthesizes 5-carbon sugars.
3) It plays essential roles in providing NADPH for biosynthetic processes, generating ribose 5-phosphate for nucleotide synthesis, and maintaining redox balance. Overall, it is a critical metabolic pathway that contributes to various cellular functions.
AMPHIBOLIC ROLE OF KREBS CYCLE WITH SPECIAL REFERENCE TO ANAPLEROTIC REACTIONS
The document discusses the amphibolic role of the Krebs cycle, specifically its anaplerotic reactions. The Krebs cycle contains both catabolic and anabolic reactions. It is amphibolic in nature. Anaplerosis refers to enzymatic reactions that replenish intermediates of the Krebs cycle from the cytosol, such as the reaction catalyzed by pyruvate carboxylase which replenishes oxaloacetate. The Krebs cycle oxidizes acetyl-CoA into carbon dioxide and water while generating reduced coenzymes that are reoxidized to produce ATP. It also provides precursors for biosynthetic pathways through anabolic reactions.
Pyruvate Dehydrogenase complex and its significance
The pyruvate dehydrogenase complex (PDH) catalyzes the irreversible oxidative decarboxylation of pyruvate to form acetyl-CoA. PDH is an assembly of three individual enzymes - pyruvate dehydrogenase (E1), dihydrolipoyl transacetylase (E2), and dihydrolipoyl dehydrogenase (E3) - that work together to decarboxylate and oxidize pyruvate, transfer the acetyl group to CoA, and reoxidize dihydrolipoamide. PDH plays an important role in linking glycolysis to the citric acid cycle by converting pyruvate to acetyl-CoA in cells containing mitochondria.
Oxidative phosphorylation and energy calculation of aerobic respiration
Oxidative phosphorylation occurs in the inner mitochondrial membrane and is the final step of aerobic respiration. It uses the energy from electron transport to power the formation of ATP from ADP and phosphate. There are four enzyme complexes involved: Complex I transfers electrons from NADH to ubiquinone while pumping protons; Complex II transfers electrons from FADH2 to ubiquinone without pumping protons. Complex III pumps protons while passing electrons from ubiquinone to cytochrome c. Complex IV passes electrons from cytochrome c to oxygen to produce water, pumping protons in the process. Through oxidative phosphorylation, the full oxidation of one glucose molecule can yield 33 ATP molecules.
Photorespiration & functioning of Rubisco enzyme
This document summarizes the process of photorespiration in plants. It begins by stating that photorespiration is a metabolic pathway where plants release carbon dioxide, consume oxygen, and do not produce biochemical energy. It then describes how photorespiration is catalyzed by the RUBISCO enzyme and involves three organelles: the chloroplast, peroxisome, and mitochondria. The key stages of the process are outlined, including how RUBISCO can fix oxygen instead of carbon dioxide, leading to the production and movement of intermediates between the organelles before ultimately being converted back to carbon dioxide and consuming energy. The document notes that photorespiration is a wasteful process for plants as it decreases photos
Recent advances in respiration in Arabidopsis thaliana
This document discusses recent advances in respiration research in the model organism Arabidopsis thaliana. It describes how A. thaliana is used as a model organism due to its small genome, rapid lifecycle, self-pollination, and experimental accessibility. The document outlines the key processes in respiration, including glycolysis, the TCA cycle, and oxidative phosphorylation. It summarizes recent research findings on how specific glycolytic enzymes impact processes like stomatal movement, flowering, and stress responses. The conclusion states that while no major breakthroughs have occurred, research focuses on understanding the molecular mechanisms and regulation of plant respiration and its role in growth, development, and environmental responses.

It discusses the history, components, and how GPS works using satellites and devices. Finally, the document outlines applications and advantages of both GIS and GPS, as well as potential disadvantages and future expansion.
Photosynthesis in higher plants
Photosynthesis is the process by which plants synthesize carbohydrates from carbon dioxide, water, and sunlight. It is significant as it maintains oxygen levels in the atmosphere, provides both direct and indirect food sources for humans and animals, and has created fossil fuel reserves like coal and oil. The key reaction of photosynthesis occurs in the chloroplasts of plant leaves where chlorophyll and other pigments absorb sunlight and convert it into chemical energy that is used to produce glucose and oxygen from carbon dioxide and water.
Inferior ovary
The document discusses inferior ovaries in plants. It defines an inferior ovary as one where the internal wall of the thalamus is fused with the wall of the ovary, so only the style and stigma are visible from above. Flowers with this structure are called epigynous. Examples given are apple, sunflower, cucumber and guava. There are two theories for the development of inferior ovaries - the appendicular theory which proposes the ovary develops from the receptacle appendages, and the receptacular theory or axial theory which proposes the ovary develops from the receptacle itself.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
