คำอธิบาย

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

α-Amylase is used to hydrolyze α bonds of α-linked polysaccharides, such as starch and glycogen. α-Amylase has been used in various plant studies, such as metabolism studies in Arabidopsis . Amylases from Aspergillus oryzae are commonly used as baking additives to prevent staling in the baking industry, clarify haze from fruit juices and alcoholic beverages, and to produce glucose and maltose syrup products .

Biochem/physiol Actions

α-Amylase 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. The International Union of Immunological Societies (IUIS) has classified α-amylase from Aspergillus oryzae (Asp o II) as an occupational allergen that can cause respiratory symptoms .

Physical form

powder

Analysis Note

Crude

Other Notes

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