WebDec 2, 2024 · Glycogen is comprised of glucose residues that are assembled into a very large, branched polymer of up to 55,000 residues. Glucose residues are connected by α-1,4-glycosidic linkages in the linear chains and by α-1,6-glycosidic bonds at the branch points. Glycogen serves as a mobilized storage form of glucose predominantly found in the liver ... WebMay 8, 2024 · Branching subsequently occurs via a glycogen branching enzyme, which has two catalytic activities, which include a transferase and alpha-1,6 glycosidase that forms the branch bond. Once the glycogen …
