So two categories are disaccharidases and peptidases. And both of these proteolytic enzymes are found at the brush border at the Villai of our small intestine. So disaccharidases are those proteolytic digestive enzymes that break down our disaccharides. So sugars that consists of two individual monomers. So three important types of disaccharidases that you should be familiar with is Maltase which breaks down maltose. We have Succeeds which breaks down sucrose and we have Lactase, which breaks down lactose.
