Dipeptidases dehydrate (to break a bond apart with water) bound pairs of amino acids called dipeptides and can be found within the enterocytes themselves.
Dipeptidases hydrolyze bound pairs of amino acids, called dipeptides. Dipeptidases are also found within the enterocytes themselves, performing cytosolic digestion of absorbed dipeptides. Usually hydrolysis is a chemical process in which a molecule of water is added to a substance. It breaks a chemical bond in the compound.
