DescriptionD-4'-Phosphopantothenate belongs to the class of organic compounds known as beta amino acids and derivatives. These are amino acids having a (-NH2) group attached to the beta carbon atom. D-4'-Phosphopantothenate is an extremely weak basic (essentially neutral) compound (based on its pKa). D-4'-Phosphopantothenate exists in all living species, ranging from bacteria to humans. Within yeast, D-4'-phosphopantothenate participates in a number of enzymatic reactions. In particular, D-4'-phosphopantothenate can be biosynthesized from pantothenic acid through its interaction with the enzyme pantothenate kinase. In addition, D-4'-phosphopantothenate, cytidine triphosphate, and L-cysteine can be converted into cytidine monophosphate and 4'-phosphopantothenoylcysteine through its interaction with the enzyme phosphopantothenate-cysteine ligase. In yeast, D-4'-phosphopantothenate is involved in the metabolic pathway called the beta-alanine metabolism pathway.
