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 the polysaccharides chitosan and chitin which compose the exoskeletons of crustaceans and other arthropods as well as the cell walls of fungi and many higher organisms. Glucosamine is one of the most abundant monosaccharides.
