[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.
1937Enzymologia II. 160 Phosphorolysis is an enzymic process. 1946Nature 23 Nov. 746/2 It was suggested that the coenzyme in muscle, while taking up two hydrogen atoms in the pyridine nucleus through the addition of free phosphate, undergoes a phosphorolysis and is split into pyridin[e] nucleotide and adenosine diphosphoric or triphosphoric acid. 1970R. 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.
Hence ˌphosphoroˈlytic a.
