[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is a very long-chain fatty acid anion that is the conjugate base of gondoic acid, formed by deprotonation of the carboxylic acid group. It has a role as a plant metabolite and a human metabolite. It is an unsaturated fatty acid anion, an icosanoid anion, a long-chain fatty acid anion and an icosenoate. It is a conjugate base of an (11Z)-icos-11-enoic acid."}, {"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-1]"}]
