Task: Please create a text description for a molecule.
Molecule SMILES: C[C@H](CCCCCCCCCCCCCCC/C=C/C(=O)O)O[C@@H]1O[C@@H](C)[C@H](O)C[C@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is an (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (2E,19R)-19-hydroxyicos-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 derives from a (2E,19R)-19-hydroxyicos-2-enoic acid. It is a conjugate acid of an ascr#35(1-).
