The molecule is an (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (16R)-16-hydroxymargaric 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 (16R)-16-hydroxymargaric acid. It is a conjugate acid of an ascr#30(1-).
(16R)-16-[(2R,3R,5R,6S)-3,5-dihydroxy-6-methyloxan-2-yl]oxyheptadecanoic acid
