Found within the cell membrane of these small intestinal cells. Now, these dying trippeptides inside the cytoplasm, they're further cleaved into amino acids. And then those amino acids, in combination of these amino acids, are transported into the bloodstream, in the bloodstream. Then they move to their target location, their target cell. Now, the other pathway by which we attain these 20 amino acids is by breaking down the existing proteins that are found inside our body. So we have proteins found inside the cells as well as outside the cells.
