"Webthe classical glycogen biosynthetic pathway is not as universal as was thought. Glycogen is a largely soluble a-linked glucose polymer (or a-glucan) with ~90% a-1,4-links in its backbone and ~10% a-1,6-linked branches (reviewed by Preiss, 2009). Glycogen can comprise hundreds of thousands of glucose " - Glycogen pathway enzymes
