WebThe partially purified α-amylase using a maize starch affinity method exhibited an optimum pH and temperature of 6.0 and 60°C, respectively. The enzyme retained 72% of its activity in the presence of 1.5 M NaCl. Scanning electron micrographs showed that the α-amylase was capable of degrading starch granules of rice and maize. WebAmylase is an enzyme that helps digest carbohydrates (starch and glycogen) into simple sugar [glucose (monosaccharide) and maltose (disaccharide)] for energy. Amylase is …

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. In humans, all amylase isoforms link to chromosome 1p21 (see AMY1A). Amylase is found in saliva and breaks starch into maltose and dextrin. This form of amylase is als…
