Calcium D(+)-pantothenate

Pantothenic acid, also called vitamin B₅ is a water-soluble B vitamin and therefore an essential nutrient. All animals require pantothenic acid in order to synthesize coenzyme A (CoA) - essential for fatty acid metabolism - as well as to in general synthesize and metabolize proteins, carbohydrates, and fats. The anion is called pantothenate.

Pantothenic acid is the combination of pantoic acid and β-alanine. Its name derives from the Greek pantos, meaning "from everywhere", as small quantities of pantothenic acid are found in nearly every food. Human deficiency is very rare. As a dietary supplement ingredient, it is commonly found as calcium pantothenate.
