Study Notes
- Biochemistry is the study of chemical processes in living organisms.
- It is a sub-discipline of both chemistry and biology.
- Biochemistry is divided into three fields: structural biology, enzymology, and metabolism.
- The study of biochemistry helps in understanding tissues, organs, and organism structure and function.
- Biochemistry deals with the structures, bonding, functions, and interactions of biological macromolecules.
- Carbohydrates, lipids, proteins, and nucleic acids are the four main classes of biomolecules.
- The six major elements that compose most of the human body are carbon, hydrogen, nitrogen, oxygen, calcium, and phosphorus.
- Carbohydrates are used for energy storage and providing structure.
- Glucose is one of the most important carbohydrates.
- A monosaccharide can switch between acyclic and cyclic forms.
- Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen.
- Monosaccharides are the simplest carbohydrates and can form disaccharides and polysaccharides through dehydration synthesis.
- Lipids are a diverse range of molecules that are largely nonpolar and hydrophobic.
- Triglycerides are the main group of bulk lipids and consist of one molecule of glycerol and three fatty acids.
- Proteins are large molecules made up of amino acids joined by peptide bonds.
- Amino acids have an alpha carbon atom attached to an amino group, a carboxylic acid group, a hydrogen atom, and a side chain.
- Proteins can have structural and/or functional roles and are composed of primary, secondary, tertiary, and quaternary structures.
- Enzymes are a type of protein that catalyze biochemical reactions in living cells.
- Ingested proteins are broken down into single amino acids or dipeptides in the small intestine and can then be used to form new proteins.
- Humans and animals cannot synthesize all the necessary amino acids and must obtain them from their diet.
- Amino acids are the building blocks of proteins.
- Some amino acids are essential and must be ingested.
- Nucleic acids are biopolymers that convey genetic information.
- The most common nucleic acids are DNA and RNA.
- Glucose is an energy source in most life forms.
- Glycolysis is a ten-step pathway that breaks down glucose.
- In aerobic cells, pyruvate is further metabolized, producing ATP and carbon dioxide.
- Gluconeogenesis is the process of converting non-carbohydrate sources to glucose.
- Biochemistry combines techniques from genetics, molecular biology, and biophysics.
- Biochemistry studies the chemistry required for biological activity of molecules.
