In molecular biology, alpha-amylase inhibitor (or α-...) is a protein family which inhibits mammalian alpha-amylases specifically, by forming a tight stoichiometric 1:1 complex with alpha-amylase. This family of inhibitors has no action on plant and microbial alpha amylases. They are found in raw plants/herbs such as cinnamon and bacteria ...
Diabetes: α-glucosidase and alpha-amylase inhibitors are found in several raw plants/herbs such as cinnamon [18] and bacteria containing acarbose [19] They are used as anti-diabetic drugs. The intake of a single dose of before a meal containing complex carbohydrates clearly suppresses the glucose spike and may decrease the postprandial ...
An inhibitor of alpha-amylase, called phaseolamin, has been tested as a potential diet aid. [10] When used as a food additive, amylase has E number E1100, and may be derived from pig pancreas or mold fungi. Bacilliary amylase is also used in clothing and dishwasher detergents to dissolve starches from fabrics and dishes.
Alpha-amylase 1 is an enzyme that in humans is encoded by the AMY1A gene. [3] This gene is found in many organisms. Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and g
Acarbose also blocks pancreatic alpha-amylase in addition to inhibiting membrane-bound alpha-glucosidases. Pancreatic alpha-amylase hydrolyzes complex starches to oligosaccharides in the lumen of the small intestine. Inhibition of these enzyme systems reduces the rate of digestion of carbohydrates.

The crystal structures of soybean trypsin inhibitor (STI), trypsin inhibitor DE-3 from the coral tree Erythrina afra (ETI) [1] and the bifunctional proteinase K/alpha-amylase inhibitor from wheat (PK13) have been solved, showing them to share the same beta trefoil fold structure as those of interleukin 1 and heparin-binding growth factors.

Pancreatic alpha-amylase is an enzyme that in humans is encoded by the AMY2A gene. [5] [6]Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and glycogen.
