Which of these chemical compounds is NOT found in gastric acid?

Sulfuric acid is not found in gastric acid, unlike hydrochloric acid which is a major component. Gastric acid, also known as stomach acid, is primarily made up of hydrochloric acid, pepsinogen (enzyme precursor), mucus, water, and electrolytes such as sodium, potassium, and chloride ions. Hydrochloric acid plays a crucial role in digestion by activating the enzyme pepsin and aiding in the breakdown of proteins. Sulfuric acid, on the other hand, is highly corrosive and not naturally produced by the stomach.
