General description

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 ethanol research. For more information see the article in biofiles.

Application

Amyloglucosidase from Aspergillus niger is used to hydrolyze α-D-glucosides. It may be used in the brewing of beer and in the production of bread and juices. Amyloglucosidase, from Sigma, has been used to hydrolyze glycogen into glucose monomers in order to study lipid accumulation in skeletal muscle .

Packaging

5 mg in glass bottle
25, 100 mg in poly bottle

Biochem/physiol Actions

Amyloglucosidase from Aspergillus niger is capable of hydrolyzing the α-D-(1-4), the α-D-(1-6), and the α-D-(1-3) glucosidic bonds of oligosaccharides. Amyloglucosidase is an extracellular enzyme that converts starch to dextrins and glucose. The enzyme is used in the starch-processing industry in the commercial production of D-glucose from corn syrup.

Unit Definition

One unit will liberate 1.0 mg of glucose from starch in 3 min at pH 4.5 at 55 °C.
