Pepsin CAS:9001-76-7 Manufacturer Price
Pepsin is a digestive enzyme found in the stomach that plays a critical role in the digestion and breakdown of proteins. It belongs to a group of enzymes called proteases, which are responsible for breaking down proteins into smaller peptides and amino acids, allowing for their absorption in the small intestine.
Pepsin is produced and secreted by the cells lining the stomach, known as chief cells, in an inactive form called pepsinogen. When food enters the stomach, it triggers the release of gastric acid, which converts pepsinogen into its active form, pepsin. Pepsin functions optimally in an acidic environment, as the low pH of the stomach helps to activate and maintain its enzymatic activity.
