Cadalene is a member of the class of compounds known as sesquiterpenoids. Sesquiterpenoids are terpenes with three consecutive isoprene units. Thus, cadalene is considered to be an isoprenoid lipid molecule. Cadalene can be found in a number of food items such as cloves, sugar apple, rosemary, and fig, which makes cadalene a potential biomarker for the consumption of these food products. Cadalene can be found primarily in saliva and urine. Cadalene exists in all eukaryotes, ranging from yeast to humans. Cadalene or cadalin (4-isopropyl-1,6-dimethylnaphthalene) is a polycyclic aromatic hydrocarbon with a chemical formula C15H18 and a cadinane skeleton. It is derived from generic sesquiterpenes, and ubiquitous in essential oils of many higher plants .
