HUMAN NUTRITION

Detailed explanation-1: -pepsin, the powerful enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, or dairy products. Pepsin is the mature active form of the zymogen (inactive protein) pepsinogen. Pepsin was first recognized in 1836 by the German physiologist Theodor Schwann.

Detailed explanation-2: -Human pepsin is one of the secondary structure proteins, whose main function is to break down proteins by hydrolyzing peptide bonds between specific amino acids, which plays an important role in the human digestive system.

Detailed explanation-3: -Pepsin is an aspartic proteinase, more specifically a eukaryotic aspartic protease enzyme. Pepsin was among the first enzymes to be isolated in crystalline form. Aspartic proteinases are widespread in nature, and pepsin in particular has been known to be medically important.
