Higher polyunsaturated fatty acids could no doubt be analysed similarly. Dienoic fatty acids present more of a problem than monoenes for the technique. The considerable increase in molecular weight means that rather high temperatures are required for GC analysis. Also, when the two double bonds are in close proximity, complications can arise in the reaction with dimethyl disulphide. |

| Although the different geometrical hot fat girls isomers have indistinguishable mass spectra, they are eluted separately from GC columns containing either polar or non-polar phases, that derived from the cis-isomer eluting first. There may be potential, therefore, to use this as an additional method for determining trans fatty acids. Also, DMDS adducts can be resolved better than the unchanged esters on GC columns, and this property has been hot fat girls used to separate and quantify petroselinic, oleic and vaccenic acids in seed oils [2]. While simpler alternatives may be available for this specific purpose, it may hot fat girls be worth keeping it mind for confirmation or for other difficult analyses. Polyunsaturated fatty acids Although the method can only be used directly with polyunsaturated fatty acids in restricted circumstances (see below), it is possible to generate monoenes from these for reaction. |
