9(E),11(E)-9-nitro Conjugated linoleic acid (9E,11E-9-nitro CLA) is a nitrated fatty acid. It is formed from 9Z,11E-CLA upon exposure to acidified nitrite, peroxynitrite, gaseous nitrogen dioxide, or a combination of myeloperoxidase, hydrogen peroxide, and nitrite.1 It is also formed in LPS-stimulated RAW 264.7 macrophages, an effect that can be reduced by the nitric oxide synthase (NOS) inhibitor L-NAME .2 9E,11E-9-nitro CLA has been found in human plasma.
