{Reference Type}: Journal Article {Title}: Fatty Acid Origin of Insect Pheromones. {Author}: Jurenka R; {Journal}: Adv Exp Med Biol {Volume}: 0 {Issue}: 0 {Year}: 2024 Jun 15 {Factor}: 3.65 {DOI}: 10.1007/5584_2024_813 {Abstract}: Pheromones are utilized to a great extent in insects. Many of these pheromones are biosynthesized through a pathway involving fatty acids. This chapter will provide examples where the biosynthetic pathways of fatty acid-derived pheromones have been studied in detail. These include pheromones from Lepidoptera, Coleoptera, and Hymenoptera. Many species of Lepidoptera utilize fatty acids as precursors to pheromones with a functional group that include aldehydes, alcohols, and acetate esters. In addition, the biosynthesis of hydrocarbons will be briefly examined because many insects utilize hydrocarbons or modified hydrocarbons as pheromones.
