Pepsin, identified by its CAS number 9001-75-6, stands as a pivotal enzyme in the complex process of digestion. As the primary protease in the stomach, its main function is to initiate the breakdown of dietary proteins into smaller peptides. This enzymatic action is fundamental for nutrient absorption and overall digestive health.

The journey of pepsin begins in the stomach's chief cells, where it's produced as an inactive precursor called pepsinogen. This zymogen form is crucial for preventing self-digestion of the stomach lining. Upon encountering the highly acidic environment of the stomach (pH 1.5-2.5), triggered by hydrochloric acid (HCl), pepsinogen undergoes a conformational change and activates into its functional form: pepsin. This process highlights the delicate pH balance required for its activity.

Pepsin's catalytic prowess lies in its ability to cleave specific peptide bonds within protein molecules, particularly those adjacent to aromatic amino acids like phenylalanine, tyrosine, and tryptophan. This makes it a potent agent for initiating protein hydrolysis. Beyond its digestive role, pepsin also contributes to antimicrobial defense by breaking down harmful microorganisms and proteins.

The significance of pepsin extends into various industrial sectors. In the food industry, it's integral to cheese production, aiding in milk curdling. The leather industry utilizes pepsin for softening animal hides and removing residual tissues. Furthermore, its role in digestive aids and pharmaceutical research underscores its versatility.
