Introduction of CEP Chondroitin Sulfate Sodium
2021-08-31 11:28:01

CEP Chondroitin Sulfate Sodium is a sodium salt of sulfated chain mucopolysaccharide extracted from cartilage tissues such as the larynx, nasal bone, and trachea of pigs. Chondroitin sulfate sodium is mainly composed of N-acetylgalactosamine (2-acetamide-2deoxy-β-D-galactopyranose) and D-glucuronic acid, the sodium salt of hexose in the copolymer It is alternately connected by β-1,3 and β-1,4 glycosidic bonds. Calculated as dry products, the sodium content of chondroitin sulfate is 95.0%-105.0% (for injection and eye drops); the sodium content of chondroitin sulfate is 85.0%-105.0% (for oral use).
