It is a metabolite of the nematode Caenorhabditis elegans. It has a role as a Caenorhabditis elegans metabolite. It is an alpha,beta-unsaturated monocarboxylic acid and an omega-hydroxy fatty acid ascaroside. It is functionally related to a (2E)-9-hydroxynon-2-enoic acid. It is a conjugate acid of an oscr#3(1-)."}]
