Vitamin B5 (Pantothenic Acid) Molecule

Pantothenic acid, also known as Vitamin B5, is a water-soluble nutrient (like all B vitamins). It is ubiquitous in living organisms, found in cells in the form of coenzyme A which is vital in the functioning of numerous enzymes. Synthetic B5 (D-pantothenic acid) is commercially available in the form of calcium pantothenate and as dexpanthenol, which is used topically to treat skin disorders.

Pantothenic acid is available in a variety of foods — as indicated by its etymological root pantos meaning `everywhere.` The vitamin can be obtained from plant and animal sources alike.
