GENERAL HISTOLOGY

Detailed explanation-1: -Gastric juice is a unique combination of hydrochloric acid (HCl), lipase, and pepsin.

Detailed explanation-2: -Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen.

Detailed explanation-3: -Gastric juice contains two main enzymes: pepsin and rennin. Pepsin breaks down proteins into short polypeptide chains while rennin coagulates the soluble milk protein, casein forming an insoluble curd which is subsequently attacked by pepsin.

Detailed explanation-4: -Gastric juice is made up of digestive enzymes, hydrochloric acid and other substances that are important for absorbing nutrients – about 3 to 4 liters of gastric juice are produced per day. The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins.

Detailed explanation-5: -An enzyme secreted from gastric glands in stomach that acts on proteins is pepsin. It is an enzyme whose zymogen/precursor (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides.
