The molecule is an (omega-1)-hydroxy fatty acid ascaroside that is ascr#18 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 as well as the sour paste nematode, Panagrellus redivivus. 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#18 and a (3R,10R)-3,10-dihydroxyundecanoic acid. It is a conjugate acid of a bhas#18(1-).
(3R,10R)-10-[(2R,3R,5R,6S)-3,5-dihydroxy-6-methyloxan-2-yl]oxy-3-hydroxyundecanoic acid
