How To Name Fatty Acids

Another systematic way of naming fatty acids would be a shorthand nomenclature which has evolved over decades where fatty acids are named by the abbreviation fa their number of carbon atoms and their number of double bonds after a colon e g fa 16 0. One system of fatty acid classification is based on the number of double bonds.

Carboxyl carbon is c 1 common nomenclature α β γ δ εetc. Fatty acids with an odd number of carbon atoms are called odd chain fatty acids whereas the rest are even chain fatty acids.

For delta nomenclature you need to know 3 things. Number of carbons from the methyl aka omega end to the first carbon in the double bond closest to the methyl end 9 if it is a saturated fatty acid then the omega nomenclature is not added to the end of the name. There are three naming systems used for fatty acids.
