Study Notes
Module 1 Material
- Chapter 1: Covers hydrolysis, compartmentation, natural selection, evolution, cell sizes, cell components, and the differences between viruses, prokaryotes, eukaryotes, and archaea, including thermodynamics and units.
Module 1 Material - Chapter 2
- Chapter 2: Focuses on the hydrophobic effect, osmosis, water structure/properties, and bonding types (hydrogen, London dispersion, hydrophobic, ionic). Key concepts include pKa, pH values, amphiphiles, and ion mobility, along with Kw values.
Module 1 Material - Chapter 3
- Chapter 3: Details amino acids (structure, groupings, pKas, modifications), protein structure, amino acid pairings, chirality, zwitterions, peptide formation, and drugs.
Module 1 Material - Chapter 4
- Chapter 4: Explores protein structure (alpha-helices, beta-sheets, beta-strands, beta-hairpins, disulfides, folding), oligomeric and globular proteins, collagen, Alzheimer's plaques, transmissible spongiform encephalopathies, prions, and 3D protein structural determination.
Module 2 Material - Chapter 9
- Chapter 9: Covers catalysis, enzyme-substrate interactions, lysozymes, serine protease (steps and tetrahedral intermediates), RNase, enzyme classification, delta-G, transition states, nucleophilicity, and metalloenzymes.
Module 2 Material - Chapter 10
- Chapter 10: Focuses on Michaelis-Menten kinetics (Km, Kcat, Vmax, Vo, etc.), inhibitors (types, plots, Ki), noncovalent modifications, and regulation in enzyme reactions, including reaction orders, rate of elementary reactions, steady-state kinetics, and ATCase's T and R states.
Module 3 Material - Chapter 5
- Chapter 5: Outlines sugar structures (structures, isomers, polymers), amylopectin, amylose, hyaluronic acid, cellulose, chitin, peptidoglycans, glycosylation, hemiacetals, uronic acid, sialic acid, and peptidoglycans, as well as artificial sweeteners.
Module 3 Material - Chapter 7
- Chapter 7: Discusses lipids (structures, locations, properties), cholesterol, and lipid bilayers.
Module 3 Material - Chapter 8
- Chapter 8: Covers transmembrane proteins, micelles, adipocytes, biconcave structure, fluid-mosaic models, translocons, vitamin D, SNAREs, I-cells, Botox, clathrin, endocytosis, and palmitolyation. It also details transporter types, uses, differences, common molecules that can pass through (neurotransmitters, gap junctions, diffusion, and aquaporins).
