[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is a polyunsaturated fatty acid anion that is the conjugate base of 12(R)-HETE, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is an icosanoid anion, a long-chain fatty acid anion, a HETE anion and a hydroxy polyunsaturated fatty acid anion. It is a conjugate base of a 12(R)-HETE."}, {"from": "gpt", "value": "[C][C][C][C][C][/C][=C][\\C][C@H1][Branch1][S][/C][=C][/C][=C][\\C][/C][=C][\\C][C][C][C][=Branch1][C][=O][O-1][O]"}]
