Long-Chain O-Ascarosyl-alkanediols Are Constitutive Components of Caenorhabditis elegans but Do Not Induce Dauer Larva Formation

Two long-chain ascarosides, O-ascarosylnonacosane-2,28-diol (1) and O-ascarosyluntriacontane-2,30-diol (2), were isolated from Caenorhabditis elegans and detected in all developmental stages of the worm The long-chain ascarosides were shown to be minor lipid components, and it was also shown that they do not induce dauer larva formation
