Describe the process of digestion of protein in stomach.
Explanation In humans, the lining of the stomach has chief cells from which the enzyme known as pepsin is released. It is an endopeptidase that breaks the peptide bond and converts the complex structure of protein into a more straightforward form. The enzyme pepsin belongs to the family aspartic protease enzyme whose function is to catalyze the reaction of acid hydrolysis of peptide bonds present between the amino acids. Pepsin is the first enzyme discovered in animals, and it only digests the proteins present in the food and does not digest the body's own protein. Final Answer The enzyme pepsin secreted into the stomach by the cells present in the inner lining of the stomach. It is an acidic protease that breaks down the complex proteins into smaller forms in the presence of hydrochloric acid and catalyses the hydrolysis of peptide bonds.
