Chondroitin sulfate belongs to a family of complex polysaccharides called glycosaminoglycans. Chondroitin sulfate consists of a long chain of repeating units of disaccharides called chondrosines. These chondrosines are composed of d-glucuronic acid and d-galactosamine. Depending on where these chondrosine units bind to each other determines which kind of chondroitin you have. Chondroitin sulfate a (also called chondroitin 4-sulfate) is the most numerous and chondroitin sulfate c (chondroitin 6-sulfate). Fibre drum/25 kg
