Metabolite Identification
Common NamePalmitone
DescriptionPalmitone, also known as 16-hentriacontane, 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. Palmitone has been detected, but not quantified in, a few different foods, such as herbs and spices, pepper (spice), and potatos (Solanum tuberosum). This could make palmitone a potential biomarker for the consumption of these foods. Palmitone is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Palmitone.
