α-Amylase is an enzyme (EC 3.2.1.1; systematic name 4-α-D-glucan glucanohydrolase) that hydrolyses α bonds of large, α-linked polysaccharides, such as starch and glycogen, yielding shorter chains thereof, dextrins, and maltose, through the following biochemical process: [2]
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
Enzymes containing this domain belong to family 13 of the glycosyl hydrolases. The maltogenic alpha-amylase is an enzyme which catalyses hydrolysis of (1-4)-alpha-D-glucosidic linkages in polysaccharides so as to remove successive alpha-maltose residues from the non-reducing ends of the chains in the conversion of starch to maltose.
Glucan 1,4-alpha-maltohydrolase (EC 3.2.1.133, maltogenic alpha-amylase, 1,4-alpha-D-glucan alpha-maltohydrolase) is an enzyme with systematic name 4-alpha-D-glucan alpha-maltohydrolase. [ 1 ] [ 2 ] This enzyme catalyses the following chemical reaction
Salivary alpha amylase levels have been found to correlate with heightened autonomic nervous system activity levels, reacting in similar ways to the hormone norepinephrine. [16] Subsequent findings reveal a relationship between α-amylase and competition.
Glucan 1,4-α-glucosidase (EC 3.2.1.3, glucoamylase, amyloglucosidase, γ-amylase, lysosomal α-glucosidase, acid maltase, exo-1,4-α-glucosidase, glucose amylase, γ-1,4-glucan glucohydrolase, acid maltase, 1,4-α-D-glucan glucohydrolase) is an enzyme located on the brush border of the small intestine with systematic name 4-α-D-glucan glucohydrolase.
A diastase (/ ˈ d aɪ ə s t eɪ z /; from Greek διάστασις, "separation") is any one of a group of enzymes that catalyses the breakdown of starch into maltose.For example, the diastase α-amylase degrades starch to a mixture of the disaccharide maltose; the trisaccharide maltotriose, which contains three α (1-4)-linked glucose residues; and oligosaccharides, known as dextrins, that ...
