Several microorganisms make use of the anaerobic pathway for synthesizing unsaturated fatty acids. This pathway will not make use of oxygen and is depending on enzymes to insert the double bond in advance of elongation using the normal fatty acid synthesis equipment. In Escherichia coli, this pathway is effectively understood.

The ammonia needed for this method is acquired by the Haber method from nitrogen and hydrogen. Ammonia produced by the Haber system is often oxidized to nitric acid through the Ostwald procedure. Ammonia is Employed in its anhydrous form (a fuel) plus the nitric acid is concentrated. The reaction is violent owing to its highly exothermic nature. After the solution is fashioned, typically at about eighty three% focus, the surplus sodium hydroxide drinking water is evaporated off to leave an ammonium nitrate (AN) information of ninety five% to 99.
