Descrizione generale

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.

Azioni biochim/fisiol

α-Amylase is composed of 496 amino acids in a single polypeptide chain. It hydrolyzes the α-(1,4) glucan linkages in polysaccharides of three or more α-(1,4) linked D-glucose units. Natural substrates such as starch and glycogen are broken down into glucose and maltose.

Definizione di unità

One unit will liberate 1.0 mg of maltose from starch in 3 min at pH 6.9 at 20 °C.

Stato fisico

Lyophilized from Tris buffer containing NaCl and CaCl2.

Nota sulla preparazione

Prepared by modified method of Levitzki et al.
