gal·ac·tos·am·ine G0011800 (găl′ək-tō′sə-mēn′, gə-lăk-)n. An amino derivative of galactose commonly found in glycolipids.galactosamine (ɡəlækˈtəʊsəˌmiːn; ɡəlækˈtəʊzəˌmiːn) nany amino sugar derived from galactose, especially chondrosamineGalactosamine
galactosamine[gə‚lak′tō·sə‚mēn] (biochemistry) C6H14O5N A crystalline amino acid derivative of galactose; found in bacterial cell walls. Galactosamine (also chondrosamine, 2-amino-2-deoxygalactose), an amino sugar; first isolated from cartilaginous tissue. A strong base, readily soluble in water, and optically active. 
An important derivative of glactosamine is N-acetyl-galactosamine, which is present as a repeating unit in chondroitin; N-acetylgalactosamine sulfate is present in chondroitin sulfates and keratosulfate. Along with glucosamine, galactosamine is a structural element in the polysaccharide of group-specific mucoids in humans and animals and also as part of the specific polysaccharide of pneumococci. galactosamine
