WebIn reversed-phase HPLC, fatty acids are separated both by chain length and by degree of unsaturation. The first double bond reduces the effective chain length by a little less than 2 carbon units, so an 18:1 fatty acid elutes just after 16:0. A second and further double bonds have smaller effects on retention so an 18:3 fatty acid elutes just ...
