The molecule is an amino octasaccharide comprising three D-GlcNS(6S) residues, one D-GlcNS(6S) residue, two D-GlcA(2S) residues and two D-GlcA residues (with one at the reducing end joined to 4-nitrophenol via a glycosidic linkage). It is an amino octasaccharide, a carbohydrate acid derivative and an oligosaccharide sulfate.
