Chondroitin sulfate A sodium salt from bovine trachea

lyophilized powder, BioReagent, suitable for cell culture

Synonym: Alternating Copoly β-glucuronic acid-(1→3)-N-acetyl-β-galactosamine-4-sulfate-(1→4)




Chondroitin Sulfate A is an acidic mucopolysaccharide found in cartilage, skin, cornea, and umbilical cord. It is composed of alternating N-acetylgalactosamine, D-glucuronic acid, and sulfate residues in equimolar quantities where carbon 4 of the N-acetylgalactosamines 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.

Biochem/physiol Actions

As a large, negatively charged, hydrophilic molecule that is too inflexible to fold into a compact globular structure, chondroitin sulfate molecules form porous hydrated gels, providing mechanical support to tissue and allowing rapid diffusion of water-soluble molecules and migration of cells.
