Properties: pepsinogen secreted by main cells of gastric mucosa is extracted by activation under the condition of pH 1.5 ~ 5.0. It is white or light yellow powder. The molecular weight is about 34500. Soluble in water, milky white in varying degrees, almost insoluble in alcohol, chloroform and ether. The activity of aqueous solution is destroyed quickly when heated to 70 ℃ or in alkaline solution, but the dried product can be heat-resistant to 100 ℃, with hygroscopicity, slight acid and salt taste.
Storage: 2-8 ℃.
Usage: digestive aid, used for dyspepsia caused by lack of pepsin or decreased digestive function after disease; This product can decompose the solidified protein after gastric acid into peptone, but can not further decompose it into amino acids. Its digestibility is the strongest with 0.2% ~ 0.4% hydrochloric acid (pH = 1.6 ~ 1.8).
Properties
Summary
Pepsin is the main digestive enzyme in gastric juice, which is synthesized by amino acids in the main cells of gastric gland. When digesting food, pepsin is discharged into the gastric cavity to participate in digestion. When the digestion activity stops, it is synthesized again to supplement consumption, so that pepsin can always have sufficient reserve food.
