Chondroitin Sulfate A is an acidic mucopolysaccharide found in cartilage, skin, cornea, and umbilical cord. It is composed of alternating N-acetyl galactosamine, D-glucuronic acid, and sulfate residues in equimolar quantities where carbon 4 of the N-acetyl galactosamines is sulfated.Chondroitin appears to play a regulatory role for chondrocytes, neural cells, and some tumor cells. Chondroitin sulfate B is used to study ß peptide (1-42) cytotoxicity.
