The products of digestion of alpha-amylase and alpha-dextrinase, along with dietary disaccharides are hydrolyzed to their corresponding monosaccharides by enzymes ( maltase, isomaltase, sucrase and lactase ) present in the brush border of the small intestine.

Starch is an enormous molecule made up of branching chains of glucose molecules . ?-amylase breaks down these chains from the end molecules forming links of two glucose molecules, i . e . maltose . ?-amylase cannot break down the branch points, although some help is found here through low ?-amylase activity and enzymes such as limit dextrinase.
