Chondroitin Sulfate is a kind of acid mucopolysaccharide extracted from healthy, edible and homebred animal cartilage or shark cartilage. It’s composed of Chondroitin Sulfate A, C and other various Chondroitin Sulfate. It is widely presented in fish,mammalian and bird cartilage.Chondroitin Sulfate Sodium is the sodium salt of the sulfated linear glycosaminoglycan. Chondroitin Sulfate 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. Chondrosamine moieties in the prevalent glycosaminoglycan are monosulfated primarily on position 4 and less so on position 6. Chondroitin Sulfate can be used for the auxiliary treatment of coronary heart disease, angina, myocardial infarction, coronary atherosclerosis, myocardial ischemia, prevention of the formation of atherosclerosis, and the treatment of neuralgia, arthralgia, and arthritis.
