Pepsin

Pepsin: Overview

Pepsin is the principal digestive enzyme of gastric juices.  It digests proteins at peptide bonds only, and is active in the very acidic conditions found in the stomach.  Pepsin is used most often as a digestive aid, often in combination with hydrochloric acid (HCl), to improve its activity.

Source

National Formulary (NF) grade pepsin has the ability to digest 3,000 or more times its weight in fresh egg albumin.  This is called pepsin 1:3000.  Concentrated pepsin can be 1:20,000 or more.

Function

Pepsin is the first in a series of enzymes that digest proteins.  In the stomach, protein chains bind in the deep active site groove of pepsin and are broken into smaller pieces.  Then, a variety of proteases and peptidases in the intestine finish the job.  The small fragments – amino acids and dipeptides – are then absorbed by cells for use as metabolic fuel or construction of new proteins.
