Quizplus · Accepted Answer

Pantothenic acid is a B vitamin that is a component of coenzyme A (CoA). CoA plays a crucial role in energy metabolism and is necessary for the synthesis of fatty acids, cholesterol, and some neurotransmitters. Pyridoxine (vitamin B6) is involved in amino acid metabolism, niacin (vitamin B3) plays a role in energy metabolism and DNA repair, and riboflavin (vitamin B2) is involved in energy production and antioxidant defenses. However, none of these vitamins are direct components of CoA.
