Unsaturated fatty acid contains more than 2 double bonds.
Answer:
Unsaturated fatty acids are typically biosynthesized by a unique dehydrogenation reaction called desaturation. The chemistry of this transformation is remarkable in its selectivity. The invention and application of novel mechanistic probes (deutero-, fluoro-, thia-containing substrate analogues) has led to a more sophisticated understanding of how fatty acid desaturases and related enzymes carry out their ultra-selective oxidation chemistry. The stereochemistry and order of hydrogen removal has been examined for a number of soluble and membrane-bound desaturses. Mechanistic models have been constructed to account for the results obtained. This knowledge can now be used to advance the design of medically relevant desaturase inhibitors and to guide protein engineering experiments in the area of plant biotechnology.
