Chondroitin sulfate is a sulfated glycosaminoglycan (GAG) composed of a chain of alternating sugars (N-acetylgalactosamine and glucuronic acid).

Chondroitin sulfate is an important structural component of cartilage and provides much of its resistance to compression. Along with glucosamine, chondroitin sulfate has become a widely used dietary supplement for treatment of osteoarthritis.

Chemical Structure

Chondroitin sulfate plays a central role in various biological processes, such as the function and elasticity of the articular cartilage, inflammation, cell adhesion, proliferation and differentiation. Number of commercial applications increased, due to its high biocompatibility, mainly in the engineering of biological tissues associated with the processes of bone repair, cartilage and cutaneous wound.
