POL is a common triglyceride component in seed and vegetable oils including olive, sesame, soybean, canola, corn, hazelnut, and many others. POL is one of the standard triglyceride components used for the USP analysis of sesame oil for pharmaceutical applications.

A cuticular pheromone in female fruit flies that stimulates male courtship behavior; biosynthesis appears to be mediated by an elongase with female-biased expression.

An unsaturated cuticular hydrocarbon that acts as a contact sex pheromone in Drosophila; may stimulate copulation either by itself at high concentrations or when combined with other alkenes; increases in Drosophila females immediately after copulation.

An unsaturated cuticular hydrocarbon that acts as a pheromone in some insects, including Drosophila; abundant only in males of D. melanogaster and D. sechellia; prevents or reduces male courtship behavior and increases female sexual receptivity.

A 25-C diene that is found in low abundance on cuticles of mature Drosophila females; depletion of a female-specific elongase (eloF), which leads to an increase in 7(Z),11(Z)-pentacosadiene along with a parallel decrease in 7,11-nonacosadiene, significantly reduces copulation in Drosophila.
