Stomach acid or Gastric acid is a fluid secreted by the Gastric gland in the stomach.. Its main consituent is HCl hydrochloric acid. The pH vary,from 1.5 to 3.5.
HCl is secreted by oxyntic( or parietal).. Due to its secreation, the proteins lose its three dimensional structure(means denatured) exposing peptides bond,assisting pepsin to breaks down proteins(proteolysis) into smaller units . So the main function is to help pepsin to break down protein..
The pH of stomach acid is about 1.0.

• What type of nutrients is broken down in the stomach, and what type of reaction is this?
