Pepsin splits proteins into water-soluble fragments called peptones. Although this ordinarily occurs in the stomach, it can be duplicated in a large reaction vessel on a commercial basis. Partial digestion by pepsin can be used in food applicationsâfor instance, in the processing of soy protein and gelatin.

To be more exact, pepsinogen is unactivated pepsin that can be converted into pepsin by HCl. To protect the stomach lining from HCl damage, your stomach has a mucus coat that regenerates every 2 weeks.
