The other explanation

UDPG: high-energy state of UDPG can easily be glycosylated supply of glycogen synthesis. In the synthesis of many disaccharides and polysaccharides in, UDPG plays the role of glycosylation donor. The body serving as a glucose donor. Finally, under the glycogen synthase (glycogen synthase) effect, UDPG glucose transferase to glycogen primer (primer) sugar chain ends, forming α-1,4 glycosidic bond.
