Descripción

Descripción general

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in starch hydrolysis research. For more information see the article in biofiles.

Aplicación

α-glucosidase is used for the determination of α-amylase and the synthesis of various 1′-O-sucrose and 1-O-fructose esters. It was also used in the measurement of glycosidase inhibition.

For the determination of α-amylase and the synthesis of various 1′-O-sucrose and 1-O-fructose esters

Acciones bioquímicas o fisiológicas

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.

Hydrolysis of terminal, non-reducing 1→4-linked D-glucose residues with release of D-glucose.

Envase

Sold on basis of p-nitrophenyl α-D-glucoside units.

Definición de unidad
