일반 설명
α-amylase is the main secretory protein constituent of saliva. It contains 496 amino acids and has two isoforms, glycosylated and non-glycosylated. α-amylase gene is located on human chromosome 1p21.1. α-amylase is mainly produced in pancreas and saliva.
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.
애플리케이션
α-amylase from human saliva has been used to test α-amylase inhibitors using HPLC (high performance liquid chromatography). It also has been used to study the digestibility of human milk oligosaccharides (HMO).
생화학적/생리학적 작용
α-amylase catalyses the hydrolysis of α-1,4 glycosidic linkage in oligosaccharides. It plays a crucial role in the initial digestion of starch, glycogen and polysaccharides. Elevated levels of amylase in serum is linked to acute pancreatitis.
단위 정의
One unit will liberate 1.0 mg of maltose from starch in 3 min at pH 6.9 at 20 °C.
물리적 형태
Lyophilized powder containing (NH4)2SO4 and sodium citrate
제조 메모
Chromatographically purified

Dietary fibre is fermented by the human gut flora resulting mainly in the formation of SCFA, for example, acetate, propionate and butyrate. SCFA, in particular butyrate, may be important for secondary cancer prevention by inducing apoptosis and inhibiting cell growth
