Category: mucopolysaccharides, chondroitin sulfate sodium salt is the most common and the most widely used.

Chemical nature
The unsaturated sugars produced by CS under acidic, alkaline and enzymatic hydrolysis conditions, including low-molecular-weight CS and CS oligosaccharides or disaccharides, are all related to β-elimination reactions.
The degradation degree of CS under acidic, alkaline, and neutral conditions is expressed by the UV absorbance value at 232nm. The larger the UV absorbance value, the greater the degradation degree, which reflects the stability of CS under different conditions.

Physical properties
CS is an acidic mucopolysaccharide substance extracted from animal tissues. It is a white or off-white powder; it is odorless; it has hygroscopic properties. The aqueous solution of this product is viscous and does not condense when heated. This product is easily soluble in water, but insoluble in organic solvents such as ethanol, acetone, and ether. Its salts are relatively stable to heat and will not be destroyed when heated to 80°C. Chondroitin sulfate aqueous solution is unstable when exposed to higher temperature or acid, and is mainly deacetylated or degraded into monosaccharides or polysaccharides with smaller molecular weight.
