Question

Which of the following coenzyme is a derivative of pantothenic acid (Vitamin B complex)?

• A. NAD
• B. NADP
• C. FAD
• D. CoA

Answer 1

The correct option is D CoA

Coenzymes are non-protein part of an enzyme. These are organic molecules that bind with the protein molecule to form the active enzyme.

Pantothenic acid is a water-soluble vitamin B${}_5$. It is required by the enzyme pyruvate dehydrogenase to synthesize coenzyme-A (CoA) which is a primary substrate for Kreb's cycle. Pantothenic acid is a precursor for the synthesis of coenzyme A (CoA, CoASH) and forms part of the “swinging sulfhydryl arm” of the fatty acid synthase complex.

So, the correct answer is option D.
