Glucosamine Sulphate, Chondroitin and MSM Doctor's Best Glucosamine Chondroitin & MSM is a synergistic complex of high quality nutrients. Understanding Glucosamine Sulphate and Chondroitin Sulphate and Their Roles in Joints Cartilage contains connective tissue composed of cells (chondrocytes), protein fibers (chiefly collagen) and clusters of complex molecules called "proteoglycans." Proteoglycan molecules are formed from long proteins (polypeptides) with numerous side chains. (The proteoglycan structure looks like a bottle brush). The attached side chains, chiefly chondroitin sulphate and keratin sulphate, are long polysaccharide molecules called "glycosaminoglycans". Cartilage contains collagen fibers embedded within a gel-like matrix known as "intracellular cement." Proteoglycans are the key structural component within this matrix. Chondroitin sulphate and the other glycosaminoglycans have a strong attraction for water, due to negative charges on their sulphate groups. These negativ
