The molecule is an omega-hydroxy fatty acid ascaroside that is oscr#22 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-hydroxy fatty acid ascaroside, a 3-hydroxy carboxylic acid and a monocarboxylic acid. It derives from an oscr#22 and a (3R)-3,13-dihydroxytridecanoic acid. It is a conjugate acid of a bhos#22(1-).
(3R)-13-[(2R,3R,5R,6S)-3,5-dihydroxy-6-methyloxan-2-yl]oxy-3-hydroxytridecanoic acid
