There are two things in gastric juices, Pepsin and hydrochloric acid. If one is alone, it would not do any digestion of proteins. But together, they can digest proteins.

This is the gastric juice, a mixture of hydrochloric acid and pepsin.
Gastric juice is produced in the stomach. Gastric juice is produced in the Gastric glands.
Pepsin - it breaks proteins into peptide fragments
The structure that contains gastric pits, which secrete gastric juice, is the stomach. The gastric pits are located within the lining of the stomach and house various types of cells, including parietal cells that produce hydrochloric acid and chief cells that secrete digestive enzymes. This gastric juice plays a crucial role in the digestion of food and the breakdown of proteins.
The enzyme in gastric juice that breaks down proteins is called pepsin. It is produced in an inactive form known as pepsinogen, which is activated by the acidic environment of the stomach. Pepsin cleaves the peptide bonds in proteins, facilitating digestion and allowing for the absorption of amino acids in the intestines.
The stomach contains hydrochloric acid, which mixes with the food we swallow. In the HCl enzymes are located to digest proteins. Some hormones are also found there to regulate the pH of the gastric juice.
Pancreatic juice contains enzymes that digest carbohydrates,fats, nucleic acids,and proteins.
Tears produce lysozyme to kill bacteria, gastric juice secretes Hcl that kills bacteria.
Gastric juice, which contains hydrochloric acid, plays a crucial role in breaking down food and activating digestive enzymes in the stomach. Mucus protects the stomach lining from the corrosive effects of acid. Pancreatic juice contains enzymes that further digest carbohydrates, proteins, and fats in the small intestine, while bile, produced by the liver and stored in the gallbladder, emulsifies fats, making them easier to digest and absorb. Together, these components ensure efficient digestion and nutrient absorption.
gastric juice is secreted by the walls of the stomach and it contains pepsin and dilute hydrochloric acid. Pepsin helps in breaking down proteins into pep-tones or peptides during the process of digestion in the stomach.
The component of gastric juice that acts as a hormone to stimulate gastric secretion and movement is gastrin. Released by G cells in the stomach lining, gastrin promotes the secretion of gastric acid (hydrochloric acid) from parietal cells and enhances gastric motility, facilitating digestion. Its release is triggered by the presence of food in the stomach, particularly proteins.
