Document Summary

Coh is the reducing end and can be oxidized to - cooh. Dna and rna - genetic info and translation of genetic info. Sugar and phosphate form the backbone of dna. Two types - pyrimidines (1 ring) and purines (2 rings) Nucleotides: polymerize on the phosphate of the 5" carbon to the -oh on the 3" carbon. Once one strand forms , the other strand will arrange in the anti-parrallel orientation. Major is where generally proteins bind (they fit more easily) Rna: can have its own single stranded structures, so it can form hydrogen bonds within itself, some are catalytic ribozymes. Lipids insoluble in water due to long none polar covalent bonds to carbons and hydrogens attractive to each other through weak van der waals forces. Trygylcerides: formed through glycerol back bone and three fatty acids (ester linkage) Saturated vs. unsaturated: saturated - c"s all filled with h - solids, unsaturated - double bonds - liquid due to kinks.
