[{"from": "human", "value": "Generate a molecule based on this description. The molecule is an (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (8R)-8-hydroxynonanoic acid with ascarylopyranose (the alpha anomer). A metabolite of the nematode Caenorhabditis elegans, it is the direct biosynthetic precursor to ascr#3. It has also been detected in the sour paste nematode, Panagrellus redivivus. It has a role as a Caenorhabditis elegans metabolite. It is a monocarboxylic acid and an (omega-1)-hydroxy fatty acid ascaroside. It is functionally related to an (8R)-8-hydroxynonanoic acid. It is a conjugate acid of an ascr#10(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][C][=Branch1][C][=O][O][O][O]"}]
