Desillerat vatten amylas Amylase is a digestive enzyme predominantly secreted by the pancreas and salivary glands and is present in other tissues at minimal levels. [1] Amylase was initially described in the early s and is one of the pioneering enzymes to undergo scientific investigation. 1 2 Amylas är en grupp enzymer som spjälkar kolhydrater, genom att katalysera hydrolys av α-1,4-glykosidbindningar mellan monosackarider i stärkelse och glykogen [1] [2]. Reaktionen resulterar i att substratmolekylerna sönderfaller i fragment om två glukosmolekyler, maltos, alternativt enstaka glukosmolekyler eller oligosackarider [1] [2]. 3 4 Although found in many tissues, amylase is most prominent in pancreatic juice and saliva, each of which has its own isoform of human α-amylase. They behave differently on isoelectric focusing, and can also be separated in testing by using specific monoclonal antibodies. 5 In animals, it is a major digestive enzyme, and its optimum pH is – [3] In human physiology, both the salivary and pancreatic amylases are α-amylases. The α-amylase form is also found in plants, fungi (ascomycetes and basidiomycetes) and bacteria (Bacillus). 6 Beta-amylase is found in bacteria, fungi, and plants; bacteria and cereal sources are the most heat stable. Working from the non-reducing end, β-amylase catalyzes the hydrolysis of the second α-1,4 glycosidic bond, cleaving off two glucose units (maltose) at a time. 7 8 vatten och fått gro. 9 Bain-Marie, Wasserbad, Bain-Marie sind die besten Übersetzungen von „vattenbad” aus dem Schwedisch ins Deutsch. 10 amylase, any member of a class of enzymes that catalyze the hydrolysis (splitting of a compound by addition of a water molecule) of starch into smaller carbohydrate molecules such as maltose (a molecule composed of two glucose molecules). Three categories of amylases, denoted alpha, beta, and gamma, differ in the way they attack the bonds of. 11 Amylase is a digestive enzyme predominantly secreted by the pancreas and salivary glands and is present in other tissues at minimal levels.
