Differbetween
The main difference between pepsin and trypsin is that the pepsin is secreted by the gastric glands of the stomach whereas the trypsin is secreted by the exocrine glands of the pancreas. Furthermore, pepsin functions in an acidic medium while trypsin functions in an alkaline medium.

What is the main difference between pepsin and trypsin?
It is secreted as an inactive zymogen known as pepsinogen. It is secreted as an inactive form known as trypsinogen. The one point difference between pepsin and trypsin is that pepsin is secreted in the stomach and acts only under acidic condition and trypsin is secreted in pancreas and acts under alkaline condition.
What is the function of trypsin and pepsin?
This active trypsin acts with the other two principal digestive proteinases — pepsin and chymotrypsin — to break down dietary protein into peptides and amino acids. These amino acids are essential for muscle growth, hormone production and other important bodily functions.
What are similarities and differences between pepsin and trypsin?
| Pepsin | Trypsin |
|---|---|
| It is situated in gastric glands. | It is situated in pancreas. |
| It acts only in acidic medium. | It acts in an alkaline medium. |
| It hydrolyses proteins into proteoses and peptones. | Along with chymotrypsin and carboxypeptidase, it acts on partially digested proteins in the stomach and converts them into dipeptides |
How do trypsin and pepsin work differently?
Specificity: Pepsin hydrolyzes peptide bonds between large hydrophobic amino acid residues, whereas trypsin hydrolyzes peptide bonds at the C-terminal side of lysine or arginine. Function: Pepsin acts on proteins and converts them into peptones, while trypsin converts peptones into polypeptides.
What is the definition of pepsin?
Listen to pronunciation. (PEP-sin) An enzyme made in the stomach that breaks down proteins in food during digestion. Stomach acid changes a protein called pepsinogen into pepsin.
Where is pepsin found?
Pepsin Pearls
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. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.
Does pepsin activate trypsin?
The activation of pepsinogen to pepsin makes pepsin available to catalyze pepsinogen further to cleave it into more pepsin. Trypsinogen is the inactive form of trypsin. ... The importance of trypsin is its ability to cleave other zymogens such as chymotripsinogen and procarboxypeptidase.
How can we detect the presence of pepsin?
The diagnostic test, Peptest (RD Biomed Ltd, Cottingham, UK), detects pepsin in expectorated saliva and is established as a simple, noninvasive measure of reflux of gastric contents.
Which foods contain pepsin?
Pepsin, the powerful enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, or dairy products.
Is trypsin acidic or basic?
The purified trypsin belonged to an alkaline protease, as it was highly active between pH 8.0 and 10.0 with the optimum pH of 9.0.
What is the difference between pepsin and Pepsinogen?
Pepsin refers to the chief digestive enzyme in the stomach, which breaks down proteins into polypeptides, while pepsinogen refers to the substance which is secreted by the stomach wall and converted into the enzyme pepsin by gastric acid.
What is role of hydrochloric acid in human digestive system?
The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.
