An intermediate in the phase II reaction that results in the formation of glucose conjugates of xenobiotics which contain substituents such as hydroxyl, amino or sulfhydryl groups, the O-, N-, and S-glucosides, respectively. UDPG is formed from uridine triphosphate and glucose-1- phosphate in a reaction catalyzed by the enzyme UDPG pyro_x0002_phosphorylase. Glucoside formation is common in insects and plants, whereas animals other than insects utilize uridine diphosphate glucuronic acid to form glucuronides.

Uridine diphosphate glucose (Standard) is the analytical standard of Uridine diphosphate glucose. This product is intended for research and analytical applications. Uridine diphosphate glucose is the precursor of glucose-containing oligosaccharides, polysaccharides, glycoproteins, and glycolipids in animal tissues and in some microorganisms. Uridine diphosphate glucose is an agonist of the P2Y14 receptor, a neuroimmune system GPCR.

ChEBI: UDP-alpha-D-glucose is the alpha-anomer of UDP-alpha-D-glucose. It is used in nucleotide sugars metabolism. It has a role as a fundamental metabolite. It is a conjugate acid of an UDP-alpha-D-glucose(2-).
