Answer:
Vitamin B5 (pantothenic acid)
Explanation:
Vitamin B5, or pantothenic acid, is naturally present in foods, added to foods and available as a supplement. It is used to make coenzyme A (CoA), a chemical compound that helps enzymes to build and break down fatty acids as well as perform other metabolic functions, and the acyl carrier protein, which is also involved in building fats. Pantothenic acid is found in a wide variety of foods. Bacteria in the gut can also produce some pantothenic acid but not enough to meet dietary needs.
