Physico-chemical Properties Of Chondroitin Sulfate

- Jun 19, 2017 -

In 1956, Meyer first began to study the types and content of acidic polysaccharide in different tissues, and identified the presence of CS, hyaluronic acid, and other sticky polysaccharides in the connective tissue. Chemical properties: CS in acidic, alkaline and enzymatic hydrolysis under the conditions of unsaturated sugar, including low molecular CS and CS of oligosaccharides or disaccharide are related to Shang elimination reaction. The degree of degradation of CS in acidic, alkaline and neutral conditions is indicated by ultraviolet absorbance at 232nm, the greater the UV absorbance value indicates, the greater the degree of degradation is, and the stability of CS under different conditions is reflected. Physical properties: CS is extracted from animal tissues of acidic polysaccharide-like substances, white or off-white powder; The aqueous solution of this product is viscous and does not condense. This product in water soluble, insoluble in ethanol, acetone, and ether and other organic solvents, its salts to heat more stable, heat up to 80 Shan also not be destroyed. Chondroitin sulfate aqueous solution, in the event of higher temperature or acid is unstable, mainly the deacetylation or degradation of monosaccharides or small molecular weight of polysaccharides.
