[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is an EpDPE obtained by formal epoxidation of the 16,17-double bond of docosa-4,7,10,13,16,19-hexaenoic acid. It has a role as a metabolite. It is functionally related to an all-cis-docosa-4,7,10,13,16,19-hexaenoic acid. It is a conjugate acid of a (4Z,7Z,10Z,13Z,19Z)-16,17-epoxydocosapentaenoate."}, {"from": "gpt", "value": "[C][C][/C][=C][\\C][C][C][Branch1][Ring2][O][Ring1][Ring1][C][/C][=C][\\C][/C][=C][\\C][/C][=C][\\C][/C][=C][\\C][C][C][=Branch1][C][=O][O]"}]
