Glycogenolysis is the breakdown of glycogen (n) to <scene name='94/942621/Cv/3'>glucose-1-phosphate</scene> and glycogen (n-1). Glycogen branches are catabolized by the sequential removal of glucose monomers via phosphorolysis, by the enzyme [[Glycogen Phosphorylase|glycogen phosphorylase]].

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.


Here, glycogen phosphorylase cleaves the bond linking a terminal glucose residue to a glycogen branch by substitution of a phosphoryl group for the α[1→4] linkage. Glucose-1-phosphate is converted to <scene name='94/942621/Cv/2'>glucose-1,6-bisphosphate</scene> (which often ends up in [[glycolysis]]) by the enzyme phosphoglucomutase.
