Supply chondroitin sulfate (ex bovine)

chondroitin sulfate (ex bovine) Chondroitin,hydrogen sulfate,sodium salt [9082-07-9]. »Chondroitin Sulfate Sodium 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-b-D-galactopyranose)and D-glucuronic acid copolymer.These hexoses are alternately linked b-1,4and b-1,3in the polymer.Chondrosamine moieties in the prevalent glycosaminoglycan are monosulfated primarily on position 4and less so on position 6.It contains not less than 90.0percent and not more than 105.0percent of chondroitin sulfate sodium,calculated on the dried basis. NOTE—Chondroitin Sulfate Sodium is extremely hygroscopic once dried.Avoid exposure to the atmosphere,and weigh promptly. Packaging and storage— Preserve in tight containers.
