9(Z),11(E)-Conjugatedlinoleicacid is an isomer of linoleicacid that has been found in beef and milk fat.1It binds to peroxisome proliferator-activated receptor α (PPARα; IC50= 140 nM) and activates the receptor in a reporter assay using COS-1 cells expressing mouse PPARα when used at a concentration of 100 μM.29(Z),11(E)-Conjugatedlinoleicacid inhibits TNF-α-inducedGLUT4expression and increases insulin-stimulated glucose transport in 3T3-L1 adipocytes.3Dietary administration of 9(Z)11(E)-conjugatedlinoleicacid reduces serum fasting glucose, insulin, and triglyceride levels and decreases white adipose tissue macrophage infiltration inob obmice. It also increases body weight gain and body fat in weanling mice.4[Matreya, LLC.

9(E),11(E)-ConjugatedLinoleicAcid (9(E),11(E)-CLA) belongs to a group of eight geometric isomers of linoleicacid, characterized by adjacent double bonds. This specific isomer, 9,11 all-trans linoleicacid, was first discovered in ground beef and is found in various dairy products as well. Notably, it has been shown to decrease mammary tumors in rats with dietary inclusion as minimal as 0.1%. [Matreya, LLC. Catalog No. 1181]
