摘要：

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, 12cis, 15trans containing a cis Delta 9 ethylenic bond was converted to a geometrical isomer of 20:5n-3, the 20:5 Delta 5cis, 8cis, 11cis, 14cis, 17trans. 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 9trans, 12cis, 15cis and the 18:3 Delta 9trans, 12cis, 15trans.
