Definition: chondroitin sulfate (chondroitin sulfate) refers to mucopolysaccharide and chondroitin sulfate salt made from cartilage of healthy animals (cattle, pigs, birds and other food animals).
For example, chondroitin sulfate sodium salt is mainly composed of n-acetylchondrosamine and d-gluconomic acid, and its sodium is bound to sulfate. The pentasaccharides in the chain are alternately bound to the polymer by β - 1,4 and β - 2,3.
The main mucopolysaccharides include chondroitin sulfate A (CSA) and chondroitin sulfate C (CSC). The sulfate radical of CSA type is on the 4-position carbon of n-acetylchondrosamine, and the sulfate radical of CSC type is on the 6-carbon of n-acetylchondrosamine.
