Metabolite Identification
Common NameUndecanal
DescriptionUndecanal, also known as undecyl aldehyde, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, undecanal is considered to be a fatty aldehyde lipid molecule. Undecanal is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Undecanal is a sweet, aldehydic, and citrus tasting compound. Outside of the human body, Undecanal is found, on average, in the highest concentration within corianders. Undecanal has also been detected, but not quantified in, several different foods, such as lemons, sweet basils, rocket salad (ssp.), corns, and citrus. This could make undecanal a potential biomarker for the consumption of these foods. Found in many essential oils, e.g. Citrus subspecies and oval kumquat Fortunella marginata.
