White powder, soluble in water, under the condition of pH2 A250/A260 = 0.73±0.05; A280/A260 = 0.39±0.03; Λmax = 262±1nm.
Donor substrate for glucosyltransferases. A key intermediate in the biosynthesis of glycogen.
Uridine 5'-diphosphoglucose disodium salt from baker's yeast (Saccharomyces cerevisiae) is used as a substrate:
- for the PpIRX10 enzyme activity of Arabidopsis thaliana.
- in radiometric assays of glycosyltransferases (GTs).
- in uridine diphosphate glucose (UDP-Glc)-4-epimerase assays in Arabidopsis thaliana samples.
Uridine 5'-diphosphoglucose disodium salt is a glycogen precursor. The transport of glucose from UDP-glucose to elongate glycogen chains is catalyzed by the enzyme glycogen synthase. The enzyme uridine diphosphate galactose-4-epimerase catalyzes the formation of UDP-glucose from UDP-galactose.
