The pH value of resting whole saliva is slightly acidic, which varies between pH 5.75 and 7.05, and it increases with increasing flow rate up to pH 8. Besides flow rate, the pH also depends on the concentration of salivary proteins, bicarbonate and phosphate ions that have considerable buffering capacity. Pepsin is an endopeptidase that breaks down proteins into smaller amino acids. It is produced in the chief cells of the stomach lining and is one of the main digestive enzymes in the digestivesystems of humans and many other animals, where it helps digest the proteins in food.
