The high-resolution 13C-NMR spectra of the olefinic carbons of two major n-3 polyunsaturated fatty acids of fish oils, DHA (22:6, n-3) and EPA (20:5, n-3), were recorded at 100.64 MHz in chloroform-d solutions on standard free acids, methyl esters, Atlantic tuna (Thunnus alalunga) triacylglycerols a

Chemical shifts are reported for long-chain acids, methyl esters, glycerol esters, wax esters, nitriles, amides, alcohols and acetates. These indicate the possibility of using high-resolution ]3C NMR spectroscopy for the analysis of mixtures of these types of compound.
