alpha-Amylase from human saliva, Type XIII-A, lyophilized powder, 300-1,500 units/mg protein

alpha-Amylase from human saliva, Type XIII-A, lyophilized powder, 300-1,500 units/mg protein

Application

?-Amylase is used to hydrolyze ? bonds of ?-linked polysaccharides, such as starch and glycogen. Product A1031 is from human saliva, is type IIA, and is supplied as a lyophilized powder. ?-Amylase has been used in various plant studies, such as metabolism studies in Arabidopsis . ?-Amylase from human saliva has been used to study the development of nutraceuticals, which may aid the treatment of diabetes and obesity .

Biochem/physiol Actions

?-Amylase hydrolyzes the ?-(1,4) glucan linkages in polysaccharides of three or more ?-(1,4) linked D-glucose units. Natural substrates such as starch and glycogen are broken down into glucose and maltose.

General description

Human ?-amylase is made up of 496 amino acids in a single polypeptide chain, which is encrypted on chromosome 1. These are produced either in the salivary glands or the pancreas. The salivary and pancreatic ?-amylases have homologous primary sequence but exhibit different cleavage patterns.
