Chemical Information
FooDB NameHexane
DescriptionHexane, also known as sextane, 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. Hexane exists as a clear, colorless liquid. It is a very hydrophobic molecule, practically insoluble in water. Industrially hexane is a significant constituent of gasoline. It is widely used as a cheap, relatively safe, largely unreactive, and easily evaporated non-polar solvent. Hexane (and its isomers) are used in the formulation of glues for shoes, leather products, and roofing. They are also used to extract cooking oils (such as canola oil or soy oil) from seeds, for cleansing and degreasing a variety of items, and in textile manufacturing. As a result, small amounts of hexane are present in a number of foods and cooking oils. Hexane also occurs naturally in certain plants. It is found, on average, in the highest concentration within kohlrabis stems, but it has also been detected in kiwi fruit, apricots, pomes, nuts, mushrooms, and corn. Hexane is not completely harmless. Exposure to high levels of hexane may damage the lungs and reproductive system. Inhalation of high concentrations of hexane produces first a state of mild euphoria, followed by somnolence with headaches and nausea. Hexane can cause degeneration of the peripheral nervous system (and eventually the central nervous system), starting with damage to the nerve axons. The initial reaction is oxidation of hexane by cytochrome P-450 isozymes to hexanols, predominantly 2-hexanol. 2,5-Hexanedione also reacts with lysine side-chain amino groups in axonal cytoskeletal proteins to form pyrroles. Continued exposure may lead to paralysis of the arms and legs.
