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
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
Optymalne pH i temperatura odpowiednio 6,9 i 53 °C; wapń jest wymagany do aktywności, a także zapobiega degradacji przez trypsynację; Charakterystyka.
1 U corresponds to the amount of enzyme which liberates 1 μmol maltose per minute at pH 6.9 and 25°C (starch acc. to Zulkowsky, Cat. No. 85642, as substrate)
