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.

The production of antibiotics involves complex chemical synthesis steps. Pharmaceutical intermediates are key chemical entities in these processes, participating in various reactions to form the final antibiotic molecules. These intermediates enhance reaction specificity and yield, simplify production processes, and reduce costs. For example, in the production of β-lactam antibiotics, intermediates such as 6-APA (6-Aminopenicillanic Acid) and 7-ACA (7-Aminocephalosporanic Acid) are crucial starting materials that undergo further chemical modifications to become broad-spectrum antibiotics.
