Metabolite Identification
Common NameHexadecane
DescriptionHexadecane, also known as cetan or CH3-[CH2]14-CH3, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Thus, hexadecane is considered to be a hydrocarbon lipid molecule. A straight-chain alkane with 16 carbon atoms. Hexadecane is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Hexadecane is an alkane tasting compound. Outside of the human body, Hexadecane is found, on average, in the highest concentration within black walnuts. Hexadecane has also been detected, but not quantified in, several different foods, such as allspices, cucumbers, tea, orange bell peppers, and herbs and spices. This could make hexadecane a potential biomarker for the consumption of these foods. Hexadecane, with regard to humans, has been linked to the inborn metabolic disorder celiac disease.
