α-淀粉酶 来源于猪胰腺

Pancreatic α-amylase is produced by the pancreatic acinar cells and released into the duodenum. It is a major molecule of pancreatic fluid.

α-Amylase from hog pancreas has been used:

• in the in vitro digestion system to study the hydrolysis of pea globulins
• in vitro α-amylase inhibition study
• to prepare digestive juice (salivary juice) for the in vitro model of the human digestion system

α-Amylase is a starch hydrolase, for glucose production, important for energy acquisition. It catalyzes the hydrolysis of α-1,4-glycosidic linkages in starch to form glucose, maltose, and maltotriose units. In mammals, α-amylase regulates the sugar assimilation by reducing the glucose uptake by Na⁺/glucose cotransporter 1 (SGLT1) and stimulating glycoprotein N-glycans mediated starch digestion. α-Amylase inhibitors are associated with the treatment of type 2 diabetes mellitus. α-Amylases are widely known industrial enzymes used in food, detergent, textile, fermentation, and pharmaceutical industries.

1单位酶相当于在pH 6.9和25℃条件下，每分钟释放1 μmol麦芽糖所需的酶量(淀粉符合Zulkowsky，货号85642，作为底物)

最佳酸碱度和温度分别为6.9和53℃；钙是活性所必需的，也能防止胰蛋白酶降解；表征。
