WebAmylase is an enzyme that helps digest carbohydrates (starch and glycogen) into simple sugar [glucose (monosaccharide) and maltose (disaccharide)] for energy. Amylase is made in the pancreas and the salivary glands that make saliva. Amylase is also found in microbes, plants and animals. WebMaltose is, technically, a double sugar, since it is composed of two molecules of the simple sugar glucose bonded together. The digestive enzyme maltase catalyzes a reaction in which a molecule of water is …
Web24 aug. 2024 · Maltose consists of two molecules of glucose that are linked by an α- (1,4′) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 28.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond. WebAspergillus oryzae was grown in a minimal medium supplemented with nine different carbon sources. alpha-Amylase formation was induced by starch and maltose. With glucose, no carbon catabolite repression was observed, but surprisingly alpha-amylase production was induced; all other tested carbon sources failed to influence alpha-amylase synthesis.
