<prompt> Active moiety of CoA isAcetyl groupPantothenic acidThiol of beta alanineThiol of pantothenic acid  <response>: - Synthesis of coenzyme A from pantothenate occurs in a series of reactions. Pantothenate is first phosphorylated to which cysteine is added. Decarboxylation, followed by addition of AMP moiety and a phosphate each from ATP results in coenzyme A.-Coenzyme A serves as a carrier of activated acetyl or acyl groups as thiol esters.
