Immobilized Pepsin; Pepsine from Porcine (high Activity, 1: 50000) Lyophil1
Brief Introduction
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.

Brief Introduction
Han Tian (Han Tian Fen) has been widely accepted and loved by people since Nara period in Japan. By the time of peace, it has been widely eaten as a cuisine. In the Edo period, people put the surplus foreign flour into the cold outdoors. After freezing, the chemical book became dry goods. It is said that this is the origin of cold weather. After trying to cook, the unique smell of the flour disappeared and became a transparent solid. Because it is rich in food fiber, it is also loved by people as a weight-loss and healthy food.

Brief Introduction
Chondroitin sulfate (CS) is a kind of glycosaminoglycans covalently linked to proteins to form proteoglycans. Chondroitin sulfate is widely distributed in the extracellular matrix and cell surface of animal tissues. The sugar chain is polymerized by alternating glucuronic acid and N-acetylgalactosamine, and connected to the serine residue of core protein through a sugar like link region.
Although the main chain structure of polysaccharide is not complex, it shows a high degree of heterogeneity in terms of the degree of sulfation, sulfate group and the distribution of the two differences to the re chain of isouronic acid. The fine structure of chondroitin sulfate determines the functional specificity and interaction with a variety of protein molecules.
