✦ Synopsis

Conjugated diene isomers of linoleic acid (CLA), possess anticarcinogenic and antiatherogenic properties, but little is known about their metabolism. We have recently obtained evidence that CLA present in partially hydrogenated oil can be metabolized to conjugated linolenic and eicosatrienoic acids in rat liver. In the present study, we have investigated whether CLA are metabolized in the liver of lambs, which normally consume high levels of CLA produced in the rumen and present in their diet, consisting exclusively of milk. Conjugated linolenic, eicosatrienoic, and arachidonic acids were detected in lamb liver phospholipids showing that elongation and desaturation of CLA occur also in lamb tissues, and that all metabolites maintain the conjugated diene structure.
