And once inside the lumen of the small intestine, we have other proteolytic enzymes produced by the pancreas are secreted into the lumen of the small intestine. And these proteolytic digestive enzymes essentially begin to cleave the smaller proteins into oligopeptides and free amino acids. Now, these amino acids are essentially absorbed into the cytoplasm of the small intestinal cells via special type of transport proteins. Now, what about these allegateptides? Well, oligopeptides are further digested to form dye and tripepptides by the enzymes found on the brush border of the small intestinal cells. And these dying tripepptides can be absorbed via specific types of transport protein molecules.
