Identification of novel trans isomers of 20:5n-3 in liver lipids of rats fed a heated oil

Identification of novel trans isomers of 20:5n-3 in liver lipids of rats fed a heated oil
Trans polyenoic 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 and 17 trans. In the present study, 2 new isomers were identified of eicosapentaenoic acid, the delta 11 monotrans and the delta 11, 17 ditrans isomers in liver of Wistar rats fed on a heated oil.
