Identification
Common Namecis-Citral
ClassSmall Molecule
DescriptionCitral is found in carrot. Citral, or 3,7-dimethyl-2,6-octadienal or lemonal, is either of, or a mixture of, a pair of terpenoids with the molecular formula C10H16O. The two compounds are double bond isomers. The E-isomer is known as geranial or citral A. The Z-isomer is known as neral or citral B. Citral has been shown to exhibit apoptotic, anti-nociceptive and anti-inflammatory functions (1, 2, 3). Citral belongs to the family of Monoterpenes. These are compounds contaning a chain of two isoprene units.
