The molecule is a 4-O-(1H-indol-3-ylcarbonyl)ascaroside that is icas#18 in which the pro-R hydrogen beta to the carboxy group is replaced by a hydroxy group. It is a metabolite of the nematode Caenorhabditis elegans. It has a role as a Caenorhabditis elegans metabolite. It is an (omega-1)-hydroxy fatty acid ascaroside, a 3-hydroxy carboxylic acid, a 4-O-(1H-indol-3-ylcarbonyl)ascaroside and a monocarboxylic acid. It derives from a bhas#18, an icas#18 and a (3R,10R)-3,10-dihydroxyundecanoic acid.
(3R,10R)-3-hydroxy-10-[(2R,3R,5R,6S)-3-hydroxy-5-(1H-indole-3-carbonyloxy)-6-methyloxan-2-yl]oxyundecanoic acid
