Ascr#5 is a highly conserved ascaroside isolated from Caenorhabditis elegans.

ChEBI: An omega-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of 3-hydroxypropanoic acid with ascarylopyranose (the alpha anomer). A major component of the dauer pheromone of the nem tode Caenorhabditis elegans, it synergises with ascr#2 and ascr#3 as a population-density signal to promote entry into an alternate larval stage, the nonfeeding and highly persistent dauer diapause.
