一般描述
Pancreatic α-amylase is produced by the pancreatic acinar cells and released into the duodenum. It is a major molecule of pancreatic fluid.
应用
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
生化/生理作用
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.
