Task: Please create a description for a molecule based on its representation.
SMILES: C[C@H](CCCCCCCCCCCCCCCC[C@@H](O)CC(=O)O)O[C@@H]1O[C@@H](C)[C@H](O)C[C@H]1O
Constraint: Answer the question with complete sentences.
Result: The molecule is an (omega-1)-hydroxy fatty acid ascaroside that is ascr#38 in which the pro-R hydrogen that is beta to the carboxy group is replaced by a hydroxy group. 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 derives from an ascr#38 and a (3R,20R)-3,20-dihydroxyhenicosanoic acid. It is a conjugate acid of a bhas#38(1-).
