Metabolite Identification
Common NameHeptadecane
DescriptionHeptadecane, also known as CH3-[CH2]15-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, heptadecane is considered to be a hydrocarbon lipid molecule. Heptadecane is an organic compound, an alkane hydrocarbon with the chemical formula C17H36. The most compact and branched isomer would be tetra-tert-butylmethane, but its existence is believed to be impossible due to steric hindrance. The name may refer to any of 24894 theoretically possible structural isomers, or to a mixture thereof. Heptadecane is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Heptadecane is an alkane tasting compound. Outside of the human body, heptadecane has been detected, but not quantified in, several different foods, such as lemon balms, coconuts, orange bell peppers, allspices, and pepper (c. annuum). This could make heptadecane a potential biomarker for the consumption of these foods. In the IUPAC nomenclature, the name of this compound is simply heptadecane, since the other isomers are viewed and named as alkyl-substituted versions of smaller alkanes. The unbranched isomer is normal or n-heptadecane, CH3(CH2)15CH3. Indeed, it is believed to be the smallest "impossible" alkane.
