[f. phosphorus or phosphorylation + hydrolysis.]
A form of hydrolysis in which a bond in an organic molecule is broken and an inorganic phosphate group becomes attached to one of the atoms previously linked.

W. McGilvery Biochem. xv. 296 Glycogen is mainly degraded by a simple phosphorolysis of the 1 → 4 glucosidic bonds to form glucose-1-phosphate... The primary reaction is catalyzed by the enzyme, phosphorylase. |
