[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is a polyunsaturated fatty acid anion that is the conjugate base of (7Z,10Z,13Z,16Z,19Z)-docosapentaenoic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3. It has a role as a human metabolite. It is a docosapentaenoate and a (7Z,10Z,13Z,16Z,19Z)-docosapentaenoyl derivative. It is a conjugate base of a (7Z,10Z,13Z,16Z,19Z)-docosapentaenoic acid."}, {"from": "gpt", "value": "[C][C][/C][=C][\\C][/C][=C][\\C][/C][=C][\\C][/C][=C][\\C][/C][=C][\\C][C][C][C][C][C][=Branch1][C][=O][O-1]"}]
