[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is an icosanoid anion that is the conjugate base of 5(S),15(R)-DiHETE arising from deprotonation of the carboxylic acid function; major species at pH 7.3. It has a role as a human xenobiotic metabolite. It is an icosanoid anion, a long-chain fatty acid anion, a polyunsaturated fatty acid anion, a hydroxy fatty acid anion and a dihydroxyicosatetraenoate. It is a conjugate base of a 5(S),15(R)-DiHETE."}, {"from": "gpt", "value": "[C][C][C][C][C][C@H1][Branch2][Ring1][=Branch1][/C][=C][/C][=C][\\C][/C][=C][\\C][=C][\\C@H1][Branch1][=Branch2][C][C][C][C][=Branch1][C][=O][O-1][O][O]"}]
