Question

Quizplus · Accepted Answer

Glycogen synthase is the main enzyme responsible for synthesizing α-1,4-glycosidic bonds in glycogen. UDP-glucose phosphorylase is involved in the synthesis of UDP-glucose, which is the substrate for glycogen synthase, but it does not directly form α-1,4-glycosidic bonds. Branching enzyme, on the other hand, is responsible for forming α-1,6-glycosidic bonds and branching points in glycogen.
