[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is an (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (2E,6R)-6-hydroxyhept-2-enoic acid with ascarylopyranose (the alpha anomer). It is a metabolite of the nematode Caenorhabditis elegans. It has a role as a Caenorhabditis elegans metabolite. It is an alpha,beta-unsaturated monocarboxylic acid and an (omega-1)-hydroxy fatty acid ascaroside. It is functionally related to a (2E,7R)-7-hydroxyoct-2-enoic acid. It is a conjugate acid of an ascr#13(1-)."}, {"from": "gpt", "value": "[C][C@H1][C@@H1][Branch2][Ring1][N][C][C@H1][Branch2][Ring1][=Branch1][C@@H1][Branch1][Ring2][O][Ring1][=Branch1][O][C@H1][Branch1][C][C][C][C][C][/C][=C][/C][=Branch1][C][=O][O][O][O]"}]
