Glycogenolysis is the degradation pathway of glycogen - a ramified polysaccharide formed by alpha1-4 linked glucose units branching at alpha1-6 bonds - to G6P, a key molecule at the intersection of several pathways of glucose metabolism. In muscle, glycogenolysis is used to provide energy whereas liver glycogenolysis is used to supply glucose to extrahepatic tissues and organs (brain is a good example - it relies on glucose as an energy source while having a limited capacity for storing it
