Definition: | An (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (2E,8R)-8-hydroxynon-2-enoic acid with ascarylopyranose (the alpha anomer). It is a major component of the dauer pheromone, used by the nematode Caenorhabditis elegans as a population-density signal to promote entry into an alternate larval stage, the nonfeeding and highly persistent dauer diapause, and also synergises with ascr#2, ascr#4, and ascr#8 in male attraction. | ||
