Extra Details:: Pantothenic acid (vitamin B5) is a precursor in the biosynthesis of coenzyme A, which is an essential cofactor functioning as an acyl group carrier and carbonyl-activating group for the citric acid cycle and fatty acid metabolism. Two enantiomers of pantothenic acid exist, D- or L-form. D-Pantothenic acid (sodium salt) is a sodium salt form of the biologically active enantiomer of vitamin B5 and is used in the synthesis of coenzyme A. The L-form of pantothenic acid is biologically inactive and has been shown to act as an antagonist of D-pantothenic acid. The calcium salts of panthenol are commonly used for pharmaceutical preparations. Pantothenate is a component of coenzyme A and is useful in its synthesis. Pantothenic acid is also involved in the synthesis of heme, cholesterol and fatty acids. Since vitamin B5 is found in all foods, its deficiency is not commonly observed.
