One-carbon nitrogen ring bases (thymine and cytosine) covalently linked to a sugar (ribose or deoxyribose) and one to three phosphate groups; can function as extracellular messengers, antimetabolites, and chain terminators that inhibit viral DNA polymerase.
Chemical. CAS 137868-52-1. Formula C15H22N2Na2O17P2. MW 610.27. Uridine 5-diphospho-alpha-D-galactose UDP-Gal is a nucleotide sugar. UDP-Gal is a donor substrate for galactosyltransferases used in the biosynthesis of galactose-containing oligosaccharides. UDP-Gal has been used as a component in galactosyltransferase labeling buffer to prelabel terminal N-acetylglucosamine GlcNAc on immunoglobulin chains. It has also been used as a component in Hyp O-galactosyltransferase HPGT assay. Decreased red blood cell levels of UDP-Gal are found in patients with maple syrup urine disease or phenylketonuria.
