And we're also going to discuss several important hormones that basically stimulate the process of digestion that are released by the small intestine. So let's begin with the proteolytic digestive enzymes of the small intestine. So as soon as our acidic kind actually leaves the stomach and enters our small intestine, it stimulates the small intestine to secrete specialized proteolytic enzymes. 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.
