Protease 6.0

Protease 6.0 is a protein-digesting enzyme that functions optimally at a pH of 6.0. The pH of the digestive tract varies from neutral (pH 6.8-7.5) in the mouth, to very acidic (pH 2.0-4.0) in the stomach, and then back again to neutral (pH 5.5-7.0) in the intestines. Therefore, enzymes that function at a particular pH can break down food at different stages of digestion as it passes through the gastrointestinal tract 1.
