Detailed explanation-1: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase.
Detailed explanation-2: -Final product: Two glucose molecules are the final product of maltose digestion.
Detailed explanation-3: -The products of amylase digestion are maltose and maltotriose (2-and 3--1, 4–linked molecules, respectively) and -dextrins containing 1, 6-glycosidic linkages, because 1, 6-glycosidic linkages in starch cannot be hydrolyzed by amylase.
Detailed explanation-4: -amylase, any member of a class of enzymes that catalyze the hydrolysis (splitting of a compound by addition of a water molecule) of starch into smaller carbohydrate molecules such as maltose (a molecule composed of two glucose molecules).
Detailed explanation-5: -During digestion, starch is partially transformed into maltose by the pancreatic or salivary enzymes called amylases; maltase secreted by the intestine then converts maltose into glucose. The glucose so produced is either utilized by the body or stored in the liver as glycogen (animal starch).
