Hydrochloric Acid


Hydrochloric acid is secreted from parietal cells located in the lining of the stomach. By creating an acidic environment in the stomach (pH - 1.8 - 3.5), pepsinogen is converted into the enzyme pepsin. Pepsin is an active proteolytic enzyme, breaking down proteins. The parietal cells also secrete intrinsic factor, which is essential for the absorption of vitamin B12.
