And then those small peptides interact with the enzymes, the proteolytic digestive enzymes of the brush border of this microvilli, as shown here, and they break them down into tripeptides, dipeptides and amino acids. Dipeptide simply means we have a single peptide bond. So we have two amino acids in the peptide. And tripeptide means we have three peptide bonds, so we have two peptide bonds, so we have three amino acids within that peptide. So all proteins are digested by proteolytic enzymes into either amino acid constituents or dipeptides and tripeptides. And the interrogate, the cell found in the small intestine is actually capable of absorbing, not only these individual amino acids, but also our dipeptides and tripepptides.
