amylase activity
Definition
Target type: molecularfunction
Catalysis of the hydrolysis of amylose or an amylose derivative. [GOC:ai]
Amylase activity is a molecular function associated with enzymes that catalyze the hydrolysis of alpha-1,4-glycosidic linkages in starch, glycogen, and related polysaccharides. These enzymes break down complex carbohydrates into smaller sugar molecules, primarily maltose and dextrins. This process is essential for the digestion of carbohydrates in both animals and plants. Amylases are found in various organisms, including humans, animals, plants, and microorganisms. In humans, salivary amylase initiates the breakdown of starch in the mouth, while pancreatic amylase continues the process in the small intestine. Amylase activity is crucial for the absorption of glucose, the primary energy source for the body. It is also involved in various industrial processes, such as the production of sweeteners, biofuels, and pharmaceuticals.'
