BSC-2010 Study Guide - Final Guide: Cysteine, Low-Density Lipoprotein, Cytosol
Document Summary
Genomics is the study of genes within and between species. Proteomics is the study of whole sets of proteins encoded by the genome. Three domains of life: bactera, archaea, eukarya. Neutron mass ~ proton mass ~ 1. 7 x 10^-24 grams. Mass number = # protons + # neutrons in nucleus. Van der waals interactions occur between transiently positive and negative regions of molecules. Themes of life: organization, info, energy & matter, interactions, evolution. The e- of the polar covalent bond spend more time near the oxygen. Cohesion helps the transport of water against gravity. Adhesion is an attraction between different substances between water. H2o has an unusually high surface tension due to hbonds. Has a high specific heat due to hbonds. Solvent bc it forms hbonds with charged & polar covalent molecules. Concentration of h+ and oh- is 10^-7 m. Product of h times oh = 10^-14 m. Ph = -log [h+] or [h+] = 10^-ph.
