Glucosamine:"(C6H14NO5) is an amino sugar that is an important precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is commonly used as a treatment for osteoarthritis. Treatment with oral glucosamine is commonly used for the treatment of osteoarthritis. Since glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplemental glucosamine may help to rebuild cartilage and treat arthritis."
