WebBecause of its mass, muscle contains almost four times as much glycogen as the liver. Muscle glycogen is not directly available as a source of blood glucose because muscle lacks glucose-6-phosphatase. During muscular activity, glycogen is converted to lactate and then into blood glucose in the liver. Publication types Review WebGlycogen synthesis is primarily regulated by modulating the activity of glycogen synthase. This enzyme exists in two forms, dephosphorylated (active or a) and phosphorylated (inactive or b ). It is regulated by covalent modification, in an inverse direction to that of glycogen phosphorylase.
