WebJan 20, 2024 · Amylase is an enzyme that breaks down starch in the form of amylopectin and amylose. Both amylose and amylopectin are formed by alpha glucose joined together by (1-4) and (1-6) glycosidic bonds. Glycogen is no exception, just that it has more branching. WebGlycogen is also stored in skeletal muscle cells for use by those cells. Muscle cells can break down glycogen but lack glucose-6-phosphatase, the enzyme that is needed if glucose is to enter the blood stream to be used by other cells. Glycogen is also stored by other tissues in amounts smaller than in muscle.
