Nonadecane, also known as CH3-[CH2]17-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. Nonadecane is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, nonadecane is considered to be a hydrocarbon lipid molecule. Nonadecane is an alkane and bland tasting compound. nonadecane has been detected, but not quantified, in several different foods, such as pomes, watermelons, yellow bell peppers, allspices, and papaya. This could make nonadecane a potential biomarker for the consumption of these foods. Nonadecane has been linked to the inborn metabolic disorders including celiac disease.
