Branch bonds glycogen
Web2.152 Glycogen. Glycogen is similar to starch in that it is a storage form of glucose. Glycogen, however, is the carbohydrate storage form in animals, rather than plants. It is even more highly branched than amylopectin, as shown below. Like amylopectin, the branch points of glycogen are alpha 1-6 glycosidic bonds, while the linear bonds are ... WebDec 30, 2024 · A glycogen debranching enzyme is also important, as the phosphorylase is unable to work closer than five glucose residues to a branch site. Figure …
