The stomach contains hydrochloric acid, which has a pH of generally 1-3.   These optimal pH levels must be present in order for pepsin (a protein-digesting enzyme) to functâ¦ion. If the pH is not acidic, pepsin will only be present in its inactive form, pepsinogen, and protein digestion will effectively occur.   Uhh.. hope that's what you were looking for. The second part is just a bit more detail as to why the pH of stomach is important.
Your stomach secretes hydrochloric acid, but the pH of your stomach isn't necessarily the same as the pH of the acid! The pH of your stomach varies, from 1-2 up to 4-5. When you eat, the stomach releases enzymes called proteases as well as hydrochloric acid to aid in digestion.
