WebPhosphorolysis. an enzyme-catalyzed reaction for the cleavage of chemical bonds in certain biologically important compounds. The reaction involves phosphoric acid, and the phosphoryl group (—H2 PO 3) is incorporated into the reaction products. The enzymes catalyzing the reaction are known as phosphorylases. WebThe phosphorylase catalyzes a phosphorolysis reaction that yields glucose 1-phosphate. Glucose 1-phosphate is converted in glucose 6-phosphate by phosphoglucomutase. Glycogen structure Nonreducing ends are shown in red and the residue that starts a branch is shown in green. α-1,6-glucosidase is also needed for breakdown of glycogen
