Peptidase
Peptidase is also known as protease or proteinase. They are produced in the stomach, small intestine and pancreas [1] and are responsible the cleavage of peptide bonds between amino acids via hydrolysis reactions, as shown in figure 1.
Thus, they have roles in the breakdown of proteins within the body. For example, peptidases in the digestive tract break down proteins entering the body from our food releasing their constituent amino acids allowing them to be used.[3]
