The molecule is an (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (18R)-18-hydroxynonadecanoic 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-1)-hydroxy fatty acid ascaroside. It derives from a (18R)-18-hydroxynonadecanoic acid. It is a conjugate acid of an ascr#34(1-).
(18R)-18-[(2R,3R,5R,6S)-3,5-dihydroxy-6-methyloxan-2-yl]oxynonadecanoic acid
