The molecule is an omega-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of 18-hydroxyoctadecanoic acid (18-hydroxystearic 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 a monocarboxylic acid and an omega-hydroxy fatty acid ascaroside. It derives from a 18-hydroxyoctadecanoic acid. It is a conjugate acid of an oscr#32(1-).
