Papain vs. Pepsin — What’s the Difference?
2024年3月28日 · Papain is a proteolytic enzyme derived from the papaya fruit, used widely in food tenderizing and as a dietary supplement for its ability to break down tough protein fibers. On the other hand, pepsin is a crucial enzyme produced in the stomach of animals, including humans, playing an essential role in digesting dietary proteins into peptides.
Pepsin - Wikipedia
Pepsin / ˈ p ɛ p s ɪ n / 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]

Reflux Revisited: Advancing the Role of Pepsin - PMC
Gastroesophageal reflux disease is mediated principally by acid. Today, we recognise reflux reaches beyond the esophagus, where pepsin, not acid, causes damage. Extraesophageal reflux occurs both as liquid and probably aerosol, the latter with a further reach. Pepsin is stable up to pH 7 and regains activity after reacidification.
Papain - Wikipedia
Papain, also known as papaya proteinase I, is a cysteine protease (EC 3.4.22.2) enzyme present in papaya (Carica papaya) and mountain papaya (Vasconcellea cundinamarcensis). It is the namesake member of the papain-like protease family.

2022年3月4日 · Papain is a cysteine protease of the peptidase C1 family. Papain consists of a single polypeptide chain with three disulfide bridges and a sulfhydryl group necessary for activity of the enzyme. Unit Definition: One unit will hydrolyze 1.0 µmole of N-α-benzoyl-L-arginine ethyl ester (BAEE) per minute at pH 6.2 at 25 °C. Figure 1.

2023年5月1日 · 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. In response to various stimuli, small basophilic cells in the deeper layers of gastric glands, known as Chief cells, produce pepsinogen.
