The roles of maltase, pepsin, and trypsin 1Maltase - a carbohydrase enzyme. During digestion, starch is partially broken down into maltose by amylase. Maltase (which is found on the membranes of the epithelium lining the small intestine) then converts maltose into glucose. |
2Pepsin - a protease enzyme. Pepsin breaks down protein in the stomach, where the conditions are acidic. Pepsin works the best at very low pH. |
3Trypsin - also a protease enzyme. Trypsin breaks down protein in the small intestine, where the conditions are alkaline following neutralisation by bile. Trypsin works the best at high pH. |
