In glycogen synthesis,glycogen synthase catalyzes the linking of glucose units to the growing glycogen chain by the formation of α (1,4)glycosidic bonds.What is the immediate source of glucose for this reaction?

Question

Quizplus · Accepted Answer

The immediate source of glucose for the reaction catalyzed by glycogen synthase in glycogen synthesis is UDP-glucose. UDP-glucose acts as a glucosyl donor, providing the glucose unit that is added to the growing glycogen chain.
