Hydrochloric acid (HCl) is the primary mineral acid found in the human stomach.

The parietal cells in the stomach lining secrete hydrochloric acid. This acid creates a highly acidic environment (pH 1.5 to 3.5) which is essential for killing ingested microorganisms, denaturing proteins to facilitate digestion, and activating pepsinogen into pepsin, the main digestive enzyme in the stomach.

Lactic acid is produced during anaerobic respiration in muscles and some microorganisms; it is not typically found free in the stomach. Uric acid is a waste product of purine metabolism and is excreted by the kidneys. Methanoic acid (formic acid) is not found in the human stomach.
