What Is The Role Of Acid In Our Stomach

The primary role of acid in our stomach is to prevent infections in our stomach and to aid in the digestion of food. Also known as gastric juice, it is primarily composed of hydrochloric acid, sodium chloride and potassium chloride.

The acid also performs another crucial function – denaturing proteins. The digestive enzymes such as pepsin break down proteins so that it can be absorbed by the body. An average human produces around 1-5 litres of gastric acid every day.
