Definition: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 nematode 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.
Synonyms:exact_synonym: 3-[(3,6-dideoxy-alpha-L-arabino-hexopyranosyl)oxy]propanoic acid
