- An amino derivative of glucose, C6H13NO5, in which an amino group replaces a hydroxyl group. It is a component of many polysaccharides and the basic structural unit of chitin and is used as an over-the-counter dietary supplement alone or in combination with chondroitin for the treatment of joint pain in arthritis.

Glucosamine (C6H13NO5) is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is part of the structure of two polysaccharides, chitosan, and chitin. Glucosamine is one of the most abundant monosaccharides. Produced commercially by the hydrolysis of shellfish exoskeletons or, less commonly, by fermentation of a grain such as corn or wheat, glucosamine has many names depending on country. Although a common dietary supplement, there is little evidence that it is effective for relief of arthritis or pain, and is not an approved prescription drug.
