Uridine diphosphate, abbreviatedUDP, is anorganic compound. It is anester ofpyrophosphoric acid with thenucleosideuridine. UDP consists of thepyrophosphategroup, thepentosesugarribose, and thenucleobaseuracil.
UDP is an important factor inglycogenesis. Beforeglucose can be stored asglycogen in theliver andmuscles, theenzymeUDP-glucose pyrophosphorylase forms aUDP-glucose unit by combining glucose 1-phosphate withuridine triphosphate, cleaving apyrophosphate ion in the process. Then, the enzymeglycogen synthase combines UDP-glucose units to form a glycogen chain. The UDP molecule is cleaved from the glucose ring during this process and can be reused by UDP-glucose pyrophosphorylase.[1][2]
