Which of the following vitamins is the precursor of CoA?
Correct Answer: Pantothenate
Description: Pantothenate is the precursor of CoA, which paicipates in numerous reactions throughout the metabolic scheme. CoA is a central molecule of metabolism involved in acetylation reactions. Thus a deficiency of pantothenic acid would have severe consequences. There is no documented deficiency state for pantothenate, however, since this vitamin is common in foodstuffs. Note: Pantothenic acid has a central role in acyl group metabolism when acting as the pantetheine functional moiety of coenzyme A or acyl carrier protein (ACP). Ref: Bender D.A. (2011). Chapter 44.
