In the mouth salivary amylase hydrolyzes
An amylase is an enzyme that catalyses the hydrolysis of starch (Latin amylum) into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion. Foods that contain large amounts of starch but little sugar, such as rice and potatoes, may acquire a slightly sweet taste as they are chewed because amylase degrades some of t… WebApr 6, 2024 · You also produce saliva, which contains amylase that mixes with your food. Amylase is a digestive enzyme that chewing activates and which hydrolyzes or breaks downs starch into monosaccharides. Amylase breaks down starch in your mouth into a maltose, a disaccharide, which is made up of two glucose molecules.
