edit: Hydrochloric Acid is a digestive acid secreted by a healthy stomach when food is eaten. It initiates the digestion of proteins, fats, and carbohydrates and aids in the absorption of several vitamins and minerals. In addition, because HCl is a strong acid, it inhibits the growth of harmful bacteria. HCl kills various bacteria from food which may pose a health hazard, inactivates the salivary amylase from the mouth, and activates pepsin, an enzyme which starts protein digestion in the stomach. HCl also denatures protein, or chemically alters the structure of protein to make protein more digestible. Acids, chemicals, heat, and radiation are various ways proteins are denatured.

PEPSIN is an enzyme used to partially hydrolyze protein. Pepsin is released in an inactive form PEPSINOGEN. The pepsinogen reacts with HCL to form pepsin.
