General description

Uridine diphosphate (UDP)-GalNAc acts as a precursor in the biosynthesis of O-linked oligosaccharide. It also acts as a substrate for synthesis of chitin, a vital element of cell walls in fungi and of exoskeletons of arthropods and insects.

Application

Uridine 5′-diphospho-N-acetylgalactosamine disodium salt has been used as a substrate for polypeptide N-acetylgalactosaminyltransferase (ppGalNAc-T).
