詳細

General description

Pancreatic α-amylase is produced by the pancreatic acinar cells and released into the duodenum. It is a major molecule of pancreatic fluid.[1]

Application

α-Amylase from hog pancreas has been used:

• in the in vitro digestion system to study the hydrolysis of pea globulins[2]
• in vitro α-amylase inhibition study[3]
• to prepare digestive juice (salivary juice) for the in vitro model of the human digestion system[4]

Biochem/physiol Actions

α-Amylase is a starch hydrolase, for glucose production, important for energy acquisition.[5] It catalyzes the hydrolysis of α-1,4-glycosidic linkages in starch to form glucose, maltose, and maltotriose units.[1] 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.[1] α-Amylases are widely known industrial enzymes used in food, detergent, textile, fermentation, and pharmaceutical industries.[1]

Other Notes

1 Uは、pH 6.9、25°C、1分間で、1 μmolのマルトースを遊離する酵素量に相当します(starch acc. to Zulkowsky, 製品番号 No. 85642を基質として使用)。

Optimum pH and temperature 6.9 and 53 °C, respectively; calcium is required for activity and also prevents degradation by trypsin; Characterization.
