Properties

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.
