Pepsin / ˈpɛpsɪn / is an endopeptidase that breaks down proteins into smaller peptides and amino acids. It is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food. Pepsin is an aspartic protease, using a catalytic aspartate in its active site. [2]

Nov 5, 2018 · Pepsin is a digestive enzyme in the stomach that breaks down proteins into smaller units called polypeptides (or peptides or short). What gland secretes pepsin?

Pepsin is a powerful enzyme in gastric juice that digests proteins such as those in meat, seeds, and dairy products. It is the mature active form of pepsinogen, which is released into the stomach and mixed with hydrochloric acid to produce pepsin.

May 1, 2023 · Pepsin is an endopeptidase that breaks down dietary proteins reaching the stomach into amino acids. It functions by digesting peptide bonds, the predominant chemical bonds found in proteins.

Pepsin is an endopeptidase enzyme that degrades proteins into peptides. It is formed in the chief cells of the stomach lining and is one of the most important digestive enzymes in humans and many other animals' digestive systems, where it aids in the digestion of proteins.

The first animal enzyme to be discovered and crystallized, pepsin is a proteolytic enzyme that breaks down proteins into peptides. This ScienceStruck post provides information on the structure, function, and important facts about pepsin.

Feb 5, 2025 · Pepsin is an enzyme that breaks down proteins into smaller peptides and amino acids. It is one of the three principal endopeptidases in the human digestive system. It is produced in the stomach and helps digest proteins in food. The other two are chymotrypsin and trypsin.

May 1, 2023 · Gastric juice comprises water, mucus, hydrochloric acid, pepsin, and intrinsic factor. Of these five components, pepsin is the principal enzyme involved in protein digestion. It breaks down proteins into smaller peptides and amino acids that …

Apr 3, 2025 · Pepsin is a powerful proteolytic enzyme that breaks down proteins into smaller peptides. Learn how it works and why it's so important for digestion.

Aug 14, 2017 · Pepsin is an enzyme -- specifically, it's a proteolytic enzyme, meaning it helps digest proteins. Cells in the stomach secrete pepsin to help you digest the protein that you consume in food.
