The job of hydrochloric acid is done. It becomes neutralized by bicarbonate, also secreted by the pancreas. The peptide chains are broken down until they can be absorbed as individual amino acids. Protein digestion begins in the stomach with hydrochloric acid.
This diagram depicts how hydrochloride acid is excreted into the stomach, in exchange for generation of bicarbonate in the blood. The generated bicarbonate is then taken up from blood by the pancreas and excreted into the small intestine with pancreatic secretions, where it neutralizes the HCl that has entered the duodenal lumen from gastric emptying.
