what break down starch in maltose
Amylase is a enzyme that breaks down starch. It does not break it down into its monomer, glucose. Amylase hydrolyses starch into disaccharides and trisaccharides. One of those disaccharides is maltose. These disaccharides and trisaccharides are then hydrolysed by other enzymes, e.g. maltase hydrolyses maltose.
