D-Pantethine is a dimeric form of D-Pantothenic Acid, which acts as a precursor to Coenzyme A and acyl carrier proteins. It is known that the sulfhydryl group is the metabolically active part of the molecule. Coenzyme A is an essential cofactor in over 70 biological pathways such as fatty acid oxidation, carbohydrate metabolism, and amino acid catabolism. Studies conducted in vitro suggest that D-Pantethine inhibits the activity of aldehyde dehydrogenase, however related metabolites of the compound such as Taurine, D-pantetheine, Coenzyme A and D-pantothenate activate this enzyme.
