The molecule is an (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (2E,15R)-15-hydroxyhexadec-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 derives from a (2E,15R)-15-hydroxyhexadec-2-enoic acid. It is a conjugate acid of an ascr#27(1-).
(E,15R)-15-[(2R,3R,5R,6S)-3,5-dihydroxy-6-methyloxan-2-yl]oxyhexadec-2-enoic acid
