O NADPH is used as the reducing equivalent in the process. O The product detaches from the fatty acid synthase complex when the chain length is usually 18 carbons.
Coenzyme A (CoA-SH) plays an important role in the Pyruvate Dehydrogenase Complex reaction. Which is correct? Coenzyme A serves as an electron acceptor in this reaction. The hydrolysis of a CoA thioester has a positive AG", the hydrolysis is endergonic and unfavorable. Coenzyme A is derived from thiamine, a vitamin. Coenzyme A contains -SH group and can serve as an acyl group carrier.
