A 19-carbon conjugated diene, conjugated nonadecadienoic acid (CNA), inhibi
ted heparin-releasable Lipoprotein lipase and reduced lipid stores in 3T3-L
1 adipocytes similarly to conjugated linoleic acid (CLA). When fed to growi
ng mice (0.3% of diet) CNA reduced body fat by 81% whereas CLA reduced body
fat by 25%. CLA and CNA differ in length by one carbon atom so they are un
likely to share a common metabolite to account for these observations. (C)
