What happens to the pH when fatty acids are liberated by lipase?

Explanation:
When fatty acids are released by lipase, the solution becomes more acidic, so the pH decreases. Lipase hydrolyzes triglycerides to glycerol and free fatty acids; these fatty acids donate protons to the water in solution, increasing the hydrogen ion concentration. In a buffered system, the buffer will oppose the change, but with ongoing fatty acid release, the balance shifts toward more H+, and the pH drops.
