Packaging

250 units in glass bottle

Unit Definition

One unit will liberate 1.0 μmole of D-glucose from p-nitrophenyl α-D-glucoside per min at pH 6.8 at 37 °C.

Physical form

Lyophilized powder containing potassium phosphate buffer salt

Application

α-glucosidase is potential enzyme for the biosynthesis of complex carbohydrates.

Biochem/physiol Actions

α-glucosidase hydrolyzes carbohydrates by acting on 1,4-α linkages. Inhibition of α-glucosidase is a prominent target in the management of non-insulin-dependent diabetes mellitus.
