Quick Summary

Chondroitin sulfate is a type of heteropolysaccharide, which means it's made of more than one type of sugar or sugar derivative. Specifically, it's composed of glucuronic acid linked to N-acetyl-d-galactosamine.1

This molecule is a key component of cartilage and other connective tissues in animals. In joints, chondroitin sulfate, along with hyaluronic acid, contributes to the structure and function of cartilage. It is also found in tendons.1234

Chondroitin sulfate is used in dietary supplements, often to help manage symptoms of osteoarthritis.4

…connective tissue are chondroitin-4-sulfate (chondroitin sulfate A) and chondroitin-6-sulfate (chondroitin sulfate C). The sugars of the sulfates are galactosamine and glucuronate. Multiple chains of chondroitin sulfate seem to be bound to protein. These substances in solution are viscous. All substances passing to and from cells must pass through the…

Chondroitin sulfate could be described as a sulfonated form of hyaluronic acid, the characteristic constituent of synovial fluid. Its presence in the matrix of the cartilage, but not in the synovial fluid, shows…
