[a. F. glucosidase (H. Bierry 1909, in Compt. Rend. CXLIX. 315): see glucoside n., -ase.]
Any enzyme that hydrolyses a glucoside, thereby producing glucose; freq. with preceding Gr. letter, as α-glucosidase (= maltase n.), β-glucosidase (= emulsin n.).
1909tr. H. Bierry in Jrnl. Chem. Soc. XCVI. 747 The intestine of dogs contains a ferment, α-glucosidase, which decomposes α-methyl-d-glucoside. 1914Jrnl. Chem. Soc. CVI. 341 In the action of α-glucosidase on a solution of dextrose in dilute alcohol, the equilibrium is reached when the ratio of combined dextrose to free dextrose is as 32.6 : 67.4. 1929R. P.
