CHEM 153C Study Guide - Quiz Guide: Malate Synthase, Citric Acid Cycle, Acetoacetic Acid
Document Summary
Study questions and problems with answers i: compare a reaction selected from the -oxidation cycle of fatty acid oxidation or the biosynthesis of acetoacetate with a closely analogous reaction of the tricarboxylic acid cycle. Select reactions for comparison in which the chemical changes involved and the mechanistic features bear a close resemblance to one another. Illustrate the reactions and comment on the most important features they have in common. Both reactions are dehydrogenases which catalyse the removal of hydrogens from and carbons adjacent to a carboxylate or carboxylic acid derivative to generate a trans-unsaturated (e) product. Both: illustrate with structural formulas one reaction of physiological importance for each of the following cases. Coenzymes may be abbreviated in standard fashion; intermediates and mechanisms need not be indicated. In each case state briefly a function in metabolism for the reaction you have shown. enzymes are flavoproteins in which the hydrogens (2 h.
