Chondroitin sulfate sodium is generally called chondroitin sulfate, also known as chondroitin sulfate sodium salt, chondroitin sulfate calcium salt. Sodium chondroitin sulfate is a kind of mucopolysaccharide, which plays many important physiological functions. It is mainly suitable for the treatment of joint diseases. Sodium chondroitin sulfate is widely distributed in the extracellular matrix and cell surface of animal tissues, including bovine , pig, chicken, shark cartilage.
Shark Chondroitin Sulfate is an acidic mucopolysaccharide extracted from shark cartilage tissue. It is white or off-white powder; odorless; hygroscopic. The aqueous solution of this product is viscous and will not condense when heated. This product is easily soluble in water, insoluble in organic solvents such as ethanol, acetone, and ether, and its salts are relatively stable to heat, and will not be destroyed when heated up to 80°C. The aqueous solution of chondroitin sulfate is unstable in case of higher temperature or acid, mainly deacetylated or degraded into monosaccharide or polysaccharide with smaller molecular weight.
The latest research has found that if glucosamine is combined with chondroitin sulfate, it will have a complementary effect. Chondroitin sulfate can promote the penetration of glucosamine into the joints. Using chondroitin sulfate and glucosamine together can relieve pain and promote cartilage regeneration, improve bone quality, protect, reverse damage and promote the repair of articular cartilage more effectively.
