glu·cos·amine glü-'kō-sə-.mēn, -zə- n an amino derivative C6H13NO5 of glucose that occurs esp. as a constituent of polysaccharides (as chitin) in animal supporting structures and some plant cell walls

n.
the amino sugar of glucose, i.e. glucose in which the hydroxyl group is replaced by an amino group. Glucosamine is a component of mucopolysaccharide and glycoprotein: for example, hyaluronic acid, a mucopolysaccharide found in synovial fluid, and heparin.

glu·co·sa·mine (gloo-kōsґə-mēn) the amino sugar derivative of glucose, substituted at the 2 position, occurring in glycosaminoglycans and a variety of complex polysaccharides such as blood group substances. It is generally acetylated (N-acetylglucosamine).
