Biological molecules
Carbohydrates are the primary source of energy and consist of carbon, hydrogen, and oxygen in a 1:2:1 ratio. Proteins perform diverse functions for cells like metabolism, structure, and acting as enzymes or carriers, and get their name from the Greek word meaning "first". Fats are lipids that are insoluble in water and are also called triglycerides. Nucleic acids like DNA and RNA store genetic information and enable protein production.
The chemistry of the cell
The document discusses five key principles of cell chemistry:
1. The importance of carbon, which forms the basis of organic molecules due to its ability to form diverse and stable compounds through carbon-carbon and carbon-hydrogen bonds.
2. The importance of water, which serves as the universal solvent in biological systems and makes up 75-85% of cells.
3. The importance of selectively permeable membranes, which act as physical barriers that control substance exchange between the internal and external environment.
4. The importance of polymerization, which allows for the synthesis of macromolecules from smaller molecule monomers.
5. The importance of self-assembly, which specifies how macromolecules fold and interact to
The Chemistry Of The Cell
The document summarizes key topics in cell biology chemistry:
1. Carbon and water are the most important atoms/molecules in living systems. Carbon forms stable covalent bonds that are well-suited for withstanding solar radiation. Water's polarity allows it to act as a solvent and stabilize temperatures.
2. Selectively permeable membranes made of phospholipids compartmentalize cells and control material exchange. They are permeable to small molecules but block larger particles like ions.
3. Macromolecules like proteins and DNA are synthesized through polymerization of small molecule monomers like amino acids and nucleotides. This process is directed and requires energy.
The Chemical Composition of Cell
Water acts as a medium for biochemical reactions in a cell.
The elements found in very small amounts are called trace elements. Trace elements include things like copper, iodine, and iron.
Biochemistry
The document provides an overview of biochemistry and chemistry concepts. It discusses the basic units of matter like elements and atoms. It then explains chemical bonds, compounds, and mixtures. Key biomolecules like carbohydrates, lipids, proteins, and nucleic acids are introduced along with their structures and functions. Finally, it briefly covers chemical reactions, enzymes, and pH.

What is biochemistry?
Biochemistry explores chemical processes related to living organisms. It is a laboratory-based science combining biology and chemistry.
Biochemists study the structure, composition, and chemical reactions of substances in living systems and, in turn, their functions and ways to control them. Biochemistry emerged as a separate discipline when scientists combined biology with organic, inorganic, and physical chemistry. They began to study areas such as:
How living things get energy from food
The chemical basis of heredity
What fundamental changes occur in disease
Biochemistry includes the sciences of molecular biology, immunochemistry, and neurochemistry, as well as bioinorganic, bioorganic, and biophysical chemistry.
What do biochemists do?
Biochemists interact with scientists from a wide variety of other disciplines, usually on problems that are a very small piece of a very large and complex system.
Biochemists in industry are interested in specific applications that will lead to marketable products
Biochemists in academia or government labs conduct more basic and less applied research
Where is biochemistry used?
Biochemistry has obvious applications in medicine, dentistry, and veterinary medicine. Other applications include:
Food Science
Biochemists determine the chemical composition of foods, research ways to develop abundant and inexpensive sources of nutritious foods, develop methods to extract nutrients from waste products, and/or invent ways to prolong the shelf life of food products.
Agriculture
Biochemists study the interaction of herbicides/insecticides with plants and pests. They examine the structure–activity relationships of compounds, determine their ability to inhibit growth, and evaluate the toxicological effects on surrounding life.
Pharmacology, Physiology, Microbiology, Toxicology, and Clinical Chemistry
Biochemists investigate the mechanisms of drug actions; engage in viral research; conduct research pertaining to organ function; or use chemical concepts, procedures, and techniques to study the diagnosis and therapy of disease and the assessment of health.

Acids and bases are fundamental compounds found everywhere in nature and in daily life. They are responsible for many natural processes and used in many products. An acid is a compound that increases the hydrogen ion (H+) concentration in water, donating protons. A base is a compound that increases the hydroxide ion (OH-) concentration in water, accepting protons. Common acids include hydrochloric acid and citric acid, while common bases include sodium hydroxide and ammonia. The pH scale measures how acidic or basic a solution is on a scale from 0 to 14. Acid-base reactions result in neutralization and salt formation.
Biochemistry
The document provides an overview of biochemistry concepts including:
1) Atoms are the basic unit of matter and are composed of protons, neutrons, and electrons. Chemical bonds form molecules by sharing or transferring electrons.
2) Carbohydrates, lipids, proteins, and nucleic acids are the four major macromolecules that make up living things. They are formed by monomers linking through dehydration synthesis and broken down through hydrolysis.
3) Enzymes are protein catalysts that speed up biochemical reactions by lowering their activation energy. Factors like pH, temperature, and substrate/enzyme concentrations influence enzymatic reaction rates.

The human body is mostly water, with water making up 75% of lean muscle, 83% of blood, and 25% of body fat. Water is a polar molecule with partially charged atoms that allow it to interact strongly with other molecules and surfaces through adhesion and cohesion. This gives water special properties as a solvent and allows it to move through small spaces against gravity. Carbon atoms form the basis of organic molecules by bonding with themselves and other elements. The four main types of organic molecules that make up living things are carbohydrates, lipids, nucleic acids, and proteins. Carbohydrates, lipids, and proteins are polymers made of repeating monomer units, while nucleic acids are polymers of nucleotide monomers that form the genetic material

Water is essential for life and makes up about two-thirds of the human body. It has no taste or smell and exists in solid, liquid, and gas forms. Water regulates body temperature, transports nutrients and waste, cushions joints, and maintains pH levels. The pH scale measures hydrogen ion concentration from 0-14, with 7 being neutral. Acids donate protons and have a pH below 7, while bases accept protons and have a pH above 7. Buffers resist pH changes and are important for biological processes.

Introduction to biochemistry
This biology course covers topics like biochemistry, metabolism, genetics, homeostasis, and ecology. It examines the structure and functions of living matter at the molecular level, including biomolecules like proteins, lipids, nucleic acids, and carbohydrates. Key concepts covered are the levels of protein structure, structures and functions of animal, plant and prokaryotic cells, pH and buffering, and chemical reactions in living systems like oxidation, reduction, hydrolysis, and condensation.
Acids, Bases, & Salts.ppt
Acids have a pH below 7 and donate hydrogen ions in solution. They react with bases, which have a pH above 7 and accept hydrogen ions, to form neutral salts. Strong acids and bases fully ionize in water, while weak ones only partially ionize. The pH scale measures hydrogen ion concentration from 0 to 14. Buffers resist pH changes when small amounts of acids or bases are added. Digestion involves both mechanical and chemical breakdown of food, with the mouth having a neutral pH and the stomach a strongly acidic pH of around 2 to aid in protein breakdown.
