Chondroitin sulfate
A glycosaminoglycan (formerly called a mucopolysaccharide) found in cartilage, bone, blood vessels and connective tissues.
There are two forms: chondroitin sulfate A and chondroitin sulfate C.
One or both types accumulate abnormally in several of the mucopolysaccharidosis disorders.
Chondroitin sulfate B is now called dermatan sulfate
