Pantothenic acid is commonly known as which vitamin?

Explanation:
Pantothenic acid is vitamin B5. It serves as a fundamental part of coenzyme A and phosphopantetheine, making it essential for acyl-transfer reactions that drive energy metabolism, such as the formation of acetyl-CoA and the synthesis and oxidation of fatty acids. The name pantothenic reflects its widespread presence in many foods, so deficiencies are uncommon. When they do occur, symptoms can include fatigue and metabolic disturbances. For context, the other vitamins listed correspond to different letters: B1 is thiamine, B7 is biotin, and B9 is folate, which highlights why pantothenic acid is the B5 vitamin.
