[{"from": "human", "value": "Create a molecule that satisfies the conditions outlined in the description. The molecule is an (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the (omega-1)-hydroxy group of (3R,21R)-3,21-dihydroxydocosanoic 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 (omega-1)-hydroxy fatty acid ascaroside, a 3-hydroxy carboxylic acid and a monocarboxylic acid. It is functionally related to a (3R,21R)-3,21-dihydroxybehenic acid."}, {"from": "gpt", "value": "[C][C@H1][C@@H1][Branch2][Ring2][=N][C][C@H1][Branch2][Ring2][#Branch1][C@@H1][Branch1][Ring2][O][Ring1][=Branch1][O][C@H1][Branch1][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C@H1][Branch1][#Branch1][C][C][=Branch1][C][=O][O][O][O][O]"}]
