Can enzyme hydrolyze starch

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 th… WebWhat enzymes are required to completely hydrolyze starch? The enzyme amylase is secreted out of the cells (an exoenzyme) into the surrounding media, catalyzing the breakdown of starch into smaller sugars which can then be absorbed by the cells for use.
