Application Notes:
This product is a methyl ester and is ideal as a gas chromatography standard. 9(Z),11(E)-Octadecadienoic acid is a
conjugated linoleic acid (CLA), an isomer of linoleic acid. CLA is found mostly in lipids originating in ruminant animals
including dairy products. It has several biological properties including anti-carcinogenic activity, suppressing in vitro growth
of human melanoma, colorectal, and breast cancer cells, and exhibiting anti-atherogenic activity.1 It is thought that CLA itself
may not have anti-oxidant capabilities but may produce substances which protect cells from the detrimental effects of
peroxides. 9(Z),11(E)-Octadecadienoic acid is the major natural isomer of CLA constituting 73% to 93% of the total CLA in
dairy products2 and it appears to be the most biologically active isomer. It appears to enhance animal growth and inhibit
osteoclast formation and activity from human cells,3 as well as decrease LDL:HDL and total:HDL cholesterol levels in
humans.4
