[{"from": "human", "value": "Create a molecule with the structure as the one described. The molecule is an octadecanoid anion that is the conjugate base of 9,10-epoxy-18-hydroxy-(12Z)-octadecenoic acid arising from deprotonation of the carboxylic acid function; major species at pH 7.3. It is an octadecanoid anion, an epoxy fatty acid anion and an omega-hydroxy-long-chain fatty acid anion. It is functionally related to a 9(10)-EpOME(1-). It is a conjugate base of a 9,10-epoxy-18-hydroxy-(12Z)-octadecenoic acid."}, {"from": "gpt", "value": "[C][Branch2][Ring1][Ring2][C][C][C][C][C][Branch1][Ring2][O][Ring1][Ring1][C][/C][=C][\\C][C][C][C][C][O][C][C][C][C][=Branch1][C][=O][O-1]"}]
