WebOct 17, 2024 · Glycogen Structure. Glycogen is a branched biopolymer made up of linear chains of glucose residues with an average chain length of about 8 to 12 glucose units and 2,000 to 60,000 residues per glycogen molecule. Similar to amylopectin, glucose units are connected one to the next in a straight line by \(\alpha-1,4\) glycosidic bonds. ... WebGlycogen is structurally quite similar to amylopectin, although glycogen is more highly branched (8–12 glucose units between branches) and the branches are shorter. When treated with iodine, glycogen gives a reddish brown color.
