What is the chemical processing of food in the stomach?

Chemical processing of food entering the stomach is carried out with the help of gastric juice. It consists of enzymes (the main enzyme is pepsin) that break down fats and proteins, mucus (keeps the stomach lining from damage) and hydrochloric acid (promotes the breakdown of food and destroys bacteria). Its formation occurs in the glands located in the gastric mucosa. The volume of secreted gastric juice, its chemical composition directly depend on the type and volume of food that will enter the stomach.
