[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. 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."}, {"from": "gpt", "value": "[C][C][=Branch1][C][=O][N][C@@H1][C@H1][Branch2][Ring1][#Branch1][C@H1][Branch1][O][C@H1][Branch1][=Branch1][O][C][Ring1][=Branch1][O][C][O][O][S][=Branch1][C][=O][=Branch1][C][=O][O-1][O][C@H1][C@@H1][Branch1][P][C@H1][Branch1][=N][C][=C][Branch1][Ring2][O][Ring1][=Branch1][C][=Branch1][C][=O][O-1][O][O]"}]
