Protease, also known as peptidase or proteinase, is the enzyme that facilitates the digestion of proteins. Like amylase, protease is secreted by the pancreas into the small intestine. It is activated from an inactive form known as trypsinogen, which is converted into trypsin in the presence of another enzyme, enterokinase. Protease works by cleaving the peptide bonds between amino acids in proteins, breaking them down into smaller peptides and eventually into individual amino acids.
