Chemical Information
FooDB NameCuminaldehyde
DescriptionCuminaldehyde belongs to the class of organic compounds known as aromatic monoterpenoids. These are monoterpenoids containing at least one aromatic ring. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. The biosynthesis of monoterpenes is known to occur mainly through the methyl-eritritol-phosphate (MEP) pathway in the plastids. Geranyl diphosphate (GPP) is a key intermediate in the biosynthesis of cyclic monoterpenes. GPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. Cuminaldehyde, or 4-isopropylbenzaldehyde, is a natural organic compound with the molecular formula C10 H12O. It is a benzaldehyde with an isopropyl group in the 4-position. Cuminaldehyde is the biologically active constituent of Cuminum cyminum seed oil. Cuminaldehyde is a volatile compound representative of the cumin aroma. It has been detected to be present in trace amounts in the blood and milk of ewes fed with cumin seed (PMID: 8738023). In mammals, cuminaldehyde is metabolized by reduction but not by oxidation (PMID: 2815827). Cuminaldehyde is a constituent of the essential oils of eucalyptus, myrrh, cassia, and cumin, among others. It has a pleasant smell and contributes to the aroma of these oils. Cuminaldehyde can also be synthesized by the reduction of 4-isopropylbenzoyl chloride or by the formylation of cumene. It is used commercially in perfumes and other cosmetics.
