Carbohydrase is the name of a set of enzymes that catalyze 5 types of reactions, turning carbohydrates into simple sugars, from the large family of glycosidases. Carbohydrases are produced in the pancreas, salivary glands and small intestine, breaking down polysaccharides. This is because complex sugars are often insoluble (such as starch), and therefore breaking them down will make it easier for the sugars to be absorbed into the blood, through the wall of the small intestine. A carbohydrate is usually a compound consisting of carbon, hydrogen and oxygen. Carbohydrase facilitates the hydrolysis of polysaccharides into simpler sugars called Monosaccharides.
