Biological Activity: 4 (Z)-Undecenal (Z4-11Al; (Z)-4-Undecenal) is a volatile aldehyde sex pheromone produced by female Drosophila melanogaster, acting as an agonist to activate the Drosophila olfactory receptor Or69aB and eliciting flight attraction and courtship behavior in Drosophila. 4 (Z)-Undecenal also activates human OR2W1, binding to its binding site through hydrophobic interactions and hydrogen bonds. 4 (Z)-Undecenal can be used in research related to olfactory receptors and insect pheromones[1][2][3].
