    Product Description

    7(Z),11(Z)-Pentacosadiene is a 25-C hydrocarbon that is found in low abundance on cuticles of mature Drosophila females.1 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.2 This raises the possibility that 7(Z),11(Z)-pentacosadiene may act as an anti-aphrodisiac.

    WARNING This product is not for human or veterinary use.
