Chemical Information
FooDB NameN-Heneicosane
DescriptionHeneicosane, is a straight chain saturated hydrocarbon with 21 carbons that is a member of the class of compounds known as alkanes. Alkanes are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Thus, heneicosane is considered to be a hydrocarbon lipid molecule. Henicosane is a neutral, hydrophobic molecule that is insoluble in water. It exists as a clear, waxy solid. Heneicosane is a naturally occurring, waxy tasting compound that can be found in a number of food items such as orange bell pepper, yellow bell pepper, lemon balm, and pepper (c. annuum). Heneicosane is used as a pheromone by queen or king termites. It also attracts mosquitoes in the genus Aedes and can be used in mosquito baits (PMID: 24060842).
