Like starch, the glucose molecules in glycogen are linked collectively by alpha(1-4) glycosidic bonds. Starch include 20-30 % amylose, an unbranched alpha 1-four polymer of D-glucose, and 70-80% amylopectin, which consists of alpha 1-four hyperlinks with alpha 1-6 hyperlinks each 25-30 glucose residues. A small covalent change to glucose, the substitution of...
