CHEMISTRY AND BIOCHEMISTRY 153A
WHAT YOU SHOULD KNOW FOR THE FINAL
The material covered in the last 2 weeks [i.e. TCA, through Oxidative Phosphorylation] will be emphasized slightly more heavily than the material on which you have already been tested. There will be emphasis on application of the general principals of metabolism and its regulation as illustrated by these pathways. For example, you will need to understand how the thermodynamics of metabolic reactions influence opposing pathways and their regulation. You need to know TCA at the same level of detail as glycolysis. However you should also be sure to review the earlier material as well. The exam will touch on nearly every topic covered in the course.
I. STRUCTURES
YOU SHOULD BE ABLE TO DRAW:
20 protein amino acids, peptide plates, peptide
bonds, and peptide chains
straight chain and cyclic forms of glucose, mannose, galactose, fructose:
sucrose, maltose,
glucopyranosides, cellobiose, cellulose, amylose, amylopectin,
glycogen
fatty acids, glycerol, triacylglycerols, glycerophospholipids,
micelles
metabolic intermediates of glycolysis and TCA cycle and glyoxylate bypass
intermediates
"business end" of lipoamide (oxidized, reduced and acetylated)
YOU SHOULD BE ABLE TO RECOGNIZE:
secondary structures, supersecondary structures, acetals, hemiacetals, ketals, hemiketals, glycosides, ADP, ATP, Pi, NAD+, NADH, FAD, FADH2, TPP, CoA,
