| Physical and Chemical Properties | This product is pepsin extracted from the gastric mucosa of pigs, sheep or cattle. It is a white or light yellow powder. Soluble in water, the aqueous solution is acidic. Isoelectric point pH = 1. Insoluble in ethanol, chloroform, ether. Non-toxic, with a special smell of meat; It is hygroscopic. Dry enzyme is relatively stable, heating to 1000C for 10min without inactivation. The aqueous solution starts to inactivate when heated to above 700C or above pH 6.2, and is irreversibly inactivated when pH>8. It is stable in strong acidic solution, and the optimum pH is 1.5~2. Its digestibility is strongest when it contains 0.2% ~ 0.4% hydrochloric acid (pH1.6 ~ 1.8), so it is often combined with dilute hydrochloric acid. Sugar-containing gastric protein enzyme preparation: this strain of pepsin is a white or light yellow powder diluted with lactose, glucose or sucrose; it is sweet, without mildew, and has a special smell of meat; it is insoluble in ethanol, ether, and chloroform; it is hygroscopic; the aqueous solution is acidic, and lg can digest 600g of solidified egg protein. |
| Use | Digestive medicine, used for the lack of pepsin or digestive dysfunction caused by indigestion |
| What is pepsin | pepsin is the main digestive enzyme in gastric juice, which is synthesized by amino acids in the main cells of gastric glands. When food is digested, pepsin is excreted into the gastric cavity to participate in digestion, when the digestive activity is stopped, the synthesis is resumed to supplement the consumption, so that the pepsin can always have sufficient reserve grain. pepsin is the "main force" in the digestion of food, but the initial discharge from the main cell is not pepsin, but its precursor-pepsinogen. If pepsin is a small knife, Pepsinogen is like a small knife with a "knife sheath" and has no digestive function, but once you encounter an "old partner"-gastric acid and a little pepsin, there is a small knife out of the sheath, immediately into a digestive pepsin, become the "force" to digest food, "killing gas" to digest the various proteins in food, hydrolyzed protein molecules in all peptide bond attachment, the protein becomes a simple structure of the components, these relatively simple components, it is easy to be completely digested in the small intestine. pepsin and gastric acid are typical "best friends", they are the same product of gastric mucosal glands, although the subtle parts are different; Proteinogen is activated by gastric acid; Gastric acid treated protein, pepsin digestion is the most labor-saving; Gastric acid provides the most suitable working environment for pepsin; The content of pepsin is the "mirror" of the level of gastric acid ", both are" inseparable ", one is lacking, the other is often insufficient, and vice versa. |
