explain starch digestion
Firstly the enzyme amylase is produced in the mouth and the pancreas.
Amylase hydrolyses the alternate glycosidic bonds of the starch molecule to produce the dissacharide maltose.
The maltose is in turn hydrolysed into the monosaccharide alpha glucose by a second enzyme, maltase.
Maltase is produced by the lining of the intestine.
