Common NamePalmitone
DescriptionPalmitone, also known as hebtriacontanone or pentadecyl ketone, belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Thus, palmitone is considered to be an oxygenated hydrocarbon lipid molecule. A dialkyl ketone that is hentriacontane in which the hydrogens at position 16 are replaced by an oxo group. Palmitone is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Palmitone has been detected, but not quantified in, a few different foods, such as herbs and spices, pepper (spice), and potato. Palmitone is found in Adiantum caudatum , Annona macroprophyllata, Annona squamosa, Ipomoea carnea, Lindera umbellata, Liriodendron tulipifera, Litsea cubeba, Litsea pungens, Markhamia stipulata , Neolitsea sericea, Platanus orientalis , Santalum album , Symphytum tuberosum and Xylopia emarginata. Palmitone was first documented in 2001 (PMID: 11301859). This could make palmitone a potential biomarker for the consumption of these foods (PMID: 20045039) (PMID: 17260693) (PMID: 19836312).
