And together, these three proteolytic enzymes are responsible for breaking down our polypeptides into smaller peptides. And finally, these small peptides basically reach the border, the cell membrane of antaricides, and on the cell membrane on the apical side, as shown in this diagram. So this is the apical side of the interocide with, this is our entericide. And the apickle side simply means it faces the lumen portion of the small intestine. So basically, on the membrane of the apical side, we have the microvilli, which is also known as the brush water. And on this membrane, we have many peptidases that are responsible for breaking down the small peptides into amino acids, dipeptides and tripepptides.
