This product is an acidic mucopolysaccharide obtained from animal cartilage tissue. The monosaccharides in it are mainly D-glucuronic acid and 2-amino-2-deoxy-D-galactose, and have equal amounts of acetyl and sulfate groups. Contains about 50-70 disaccharide basic units, and the relative molecular mass is 10,000-300,000. The medicinal product is a mixture of chondroitin sulfate A, D, etc. Off-white amorphous powder, slightly salty; odorless; hygroscopic. The aqueous solution of this product is viscous and will not condense when heated. soluble in water
Chondroitin sulfate is divided into A, B, C, D, E, F, H according to its chemical composition and structural differences, among which B, F, and H molecules contain L-iduronic acid. B is not degraded by hyaluronidase, and its color reaction is different from that of A. B is called dermatan sulfate, which is more abundant in the skin. Medicinal chondroitin sulfate is extracted from animal cartilage, mainly A, C and a mixture of various chondroitin sulfates.
