Chemical Information
FooDB NameOctane
DescriptionOctane, also known as N-oktan or CH3-[CH2]6-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, octane is considered to be a hydrocarbon lipid molecule. Octane is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Octane is an alkane and gasoline tasting compound. Octane has been detected, but not quantified in, several different foods, such as gingers, red bell peppers, guava, green bell peppers, and pepper (c. annuum). This could make octane a potential biomarker for the consumption of these foods. Octane is a potentially toxic compound.
