Answered by admin @
Role of acid in our stomach:
During digestion process, acidic gastric juice is secreted in the stomach. In stomach the food is stored for 4-5 hours. During this period chemical digestion of food occurs. The acidic gastric juice is made up of Hydrochloric acid, mucus and bicarbonates.
The proenzyme secreted by the gastric gland of stomach gets activated into active enzyme called pepsin a proteolytic enzyme when it comes in contact with the hydrochloric acid. The acid provides the optimal temperature for the action of the pepsin and in turn pepsin converts the proteins into peptides.
Mucus and bicarbonates act as lubricators and protects the mucosal epithelium layer of stomach by getting affected by the concentrated hydrochloric acid.
