Merck, U4625-5G, Uridine 5′-diphosphoglucose disodium salt hydrate from Saccharomyces cerevisiae

General description
Uridine diphosphate glucose (UDP-glucose) is a glycogen precursor. The transfer of glucose from UDP-glucose to growing glycogen chain is catalyzed by the enzyme glycogen synthase. The enzyme uridine diphosphate galactose-4-epimerase catalyzes the formation of UDP-glucose from UDP-galactose.
Application
Uridine 5′-diphosphoglucose disodium salt hydrate from Saccharomyces cerevisiae has been used as a substrate
for the PpIRX10 enzyme activity from Arabidopsis thaliana
in radiometric assay of glycosyltransferases (GTs)
in uridine diphosphate glucose (UDP-Glc) 4-epimerase assay in Arabidopsis thaliana samples

Biochem/physiol Actions
Uridine diphosphate glucose (UDP-glucose) is an essential mediator of the cellular metabolic pathways. In yeast, the high levels of trehalose and glycogen favor increased levels of UDP-glucose.
