WebAug 15, 2024 · Function: Glycogen carbohydrate cytosolic Total glycogen storage ∼ 400–450 g provides glucose for 12–48 hours Liver: ∼ 150 g (stabilization of blood glucose when needed) Muscle: ∼ 250 g( energy storage for muscle) Extracellular matrix ∼ 15 g 0.1% of ECM Erythrocytes glycogen Chemical structure WebMoreover, CEMIP interacts with the glycogen phosphorylase kinase β-subunit (PHKB) via its C-terminal region . As a consequence, the phosphorylation of PHKB is increased, resulting in the activation of glycogen phosphorylase activity and accelerated glycogen breakdown, which promotes cancer cell survival and suppresses apoptosis [ 65 ].
