Chondroitin Sulfate Salium is the sodium salt of the sulfated linear glycosaminoglycan obtained from bovine,porcine,or avian cartilages of healthy and domestic animals used for food by humans.Chondroitin Sulfate Sodium consists mostly of the sodium salt of the sulfate ester of N-acetylchondrosamine(2-acetamido-2-deoxy-β-D-galactopyranose)and D-glucuronic acid copolymer.These hexoses are alternately linked β-1,4 and β-1,3 in the polymer.The prevalent glycosaminoglycans are designated chondroitin sulfate sodium A,containing N-acetylchondrosamine-4-O-sulfate,and chondroitin sulfate sodium C,containing N-acetylchondrosamine-6-O-sulfate.It contains not less than90.0 percent and not more than 105.0 percent of total glycosaminoglycans as chondroitin sulfate sodium,calculated on the dried basis.
