SMILES: CC(=O)N[C@@H]1[C@H]([C@H]([C@H](OC1O)CO)OS(=O)(=O)[O-])O[C@H]2[C@@H]([C@H](C=C(O2)C(=O)[O-])O)O
Description: The molecule is a carbohydrate acid derivative anion resulting from the removal of a proton from the carboxy and sulfate groups of 2-acetamido-2-deoxy-3-O-(4-deoxy-alpha-L-threo-hex-4-enopyranosyluronic acid)-4-O-sulfo-D-galactopyranose arising from deprotonation of carboxylic acid and sulfate functions. It is a carbohydrate acid derivative anion, a monocarboxylic acid anion and an organosulfate oxoanion. It is a conjugate base of a 2-acetamido-2-deoxy-3-O-(4-deoxy-alpha-L-threo-hex-4-enopyranosyluronic acid)-4-O-sulfo-D-galactopyranose.
