Abstract

Trans polyunsaturated n-3 fatty acids are formed as a result of the heat treatment of vegetable oils. It was demonstrated previously that the 18:3 delta 9cis, 12 cis, 15 trans containing a cis delta 9 ethylenic bond was converted to a geometrical isomer of 20:5n-3, the 20:5 delta 5 cis, 8 cis, 11 cis, 14 cis, 17 trans. In the present study, we have identified two new isomers of eicosapentaenoic acid, the delta 11 monotrans and the delta 11, 17 ditrans isomers in liver of rats fed a heated oil. These are formed as a result of the conversion of two of the main isomers of linolenic acid which are present in refined and frying oils, the 18:3 delta 9 trans, 12 cis, 15 cis and the 18:3 delta 9 trans, 12 cis, 15 trans.
