Chondroitin sulfate is extracted from animal cartilage preparation of acid mucopolysaccharide, mainly chondroitin sulfate A, C and various mixtures of sulfuric acid cartilage. Chondroitin sulfate widely found in animal cartilage, Hougu, nasal bone, the bone tendon, ligament, skin, cornea and other tissues also. In cartilage, chondroitin sulfate proteoglycan and protein together to form, together with collagen. Sodium Chondroitin Sulfate a white powder, odorless, tasteless, absorb water, soluble in water, insoluble in ethanol, acetone and ether and other organic solvents. Chondroitin sulfate solution, case of high temperature or acid that is unstable, mainly Deacetylation and degrade into a simple sugar or small molecular weight polysaccharides.

Chondroitin sulphate is an important component of connective tissue and is present in fish,
mammalian and bird cartilage. As an acidic polysaccharide, chondroitin sulphate is composed
of chondroitin sulphate A, C and various chondroitin sulphate. In cartilage, chondroitin sulphate assists in providing texture, elasticity and moisture binding.
