[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is a 2-acyl-sn-glycero-3-phosphoethanolamine zwitterion obtained by transfer of a proton from the phosphate to the amino group of 2-arachidonoyl-sn-glycero-3-phosphoethanolamine; major species at pH 7.3. It is functionally related to an arachidonic acid. It is a tautomer of a 2-arachidonyl-sn-glycero-3-phosphoethanolamine."}, {"from": "gpt", "value": "[C][C][C][C][C][/C][=C][\\C][/C][=C][\\C][/C][=C][\\C][/C][=C][\\C][C][C][C][=Branch1][C][=O][O][C@H1][Branch1][Ring1][C][O][C][O][P][=Branch1][C][=O][Branch1][C][O-1][O][C][C][NH3+1]"}]
