Two combined monosaccharides, (carbohydrates).

Disaccharidase is an enzyme that catalyzes the hydrolysis of disaccharides. It is produced in the small intestine and helps to digest starches and other carbohydrates.

The plasma membranes of cells in the lining of the small intestine contain brush border enzymes, which are responsible for the final breakdown of carbohydrates, proteins, and fats. Some examples of these digestive enzymes include maltase, sucrase, lactase (to break down carbohydrates), peptidase (to break down proteins), and lipase (to break down fats).

Sucrase is the enzyme (called a disaccharidase) that digests sucrose, the major disaccharide in table sugar.

The nutrients found in milk are digested by many different enzymes. Lipase acts on the fat molecules, while proteases break down protein. The main carbohydrate in milk is lactose, which is digested using the enzymes lactase.
