What is the Role of Acid in our stomach ?

Answer

The stomach has Hydrochloric acid present in it. This acid plays two important roles :

  1. It activates Pepsin , the protein digesting enzyme. Due to HCl, this enzyme can work at its optimum pH level , thus digesting proteins.
  2. HCl kills any bacteria that enter the stomach with the food, which protects from infection.
