Hexoses are monosaccharides in which the sugar unit is a is a six-carbon containing moeity. D-galactosamine is soluble (in water) and a very weakly acidic compound (based on its pKa). D-galactosamine can be found in a number of food items such as pepper (c. annuum), orange bell pepper, green bell pepper, and yellow bell pepper, which makes D-galactosamine a potential biomarker for the consumption of these food products. D-galactosamine may be a unique E.coli metabolite. D-galactosamine is a hexosamine derived from galactose with the molecular formula C6H13NO5. This amino sugar is a constituent of some glycoprotein hormones such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Other sugar constituents of FSH and LH include glucosamine, galactose and glucose . 2-Amino-2-deoxy-D-galactopyranose 2-Amino-2-deoxy-D-galactose Chondrosamine D-2-Amino-2-deoxygalactose D-chondrosamine D-Galactopyranose, 2-amino-2-deoxy- D-galactosamine D-Galactose, 2-amino-2-deoxy- Galactopyranose, 2-amino-2-deoxy-, D- Galactose, 2-amino-2-deoxy-, D- C6H13NO5 179.1711 179.079372531 (3R,4R,5R,6R)-3-amino-6-(hydroxymethyl)oxane-2,4,5-triol galactosamine 7535-00-4 N[C@H]1C(O)O[C@H](CO)[C@H](O)[C@@H]1O InChI=1S/C6H13NO5/c7-3-5(10)4(9)2(1-8)12-6(3)11/h2-6,8-11H,1,7H2/t2-,3-,4+,5-,6?/m1/s1 MSWZFWKMSRAUBD-GASJEMHNSA-N belongs to the class of organic compounds known as hexoses.
