Nitro-fatty acids (NO2-FA) are pleiotropic modulators of redox signaling pathways. Their effects on inflammatory signaling have been studied in great detail in cell, animal and clinical models primarily using exogenously administered nitro-oleic acid. While we know a considerable amount regarding NO2-FA signaling, endogenous formation and metabolism is relatively unexplored. This review will cover what is currently known regarding the proposed mechanisms of NO2-FA formation, dietary modulation of endogenous NO2-FA levels, pathways of NO2-FA metabolism and the detection of NO2-FA and corresponding metabolites.
Keywords: Diet; Metabolism; Nitration; Nitric oxide; Nitro-conjugated linoleic acid; Nitro-fatty acid; Nitrogen dioxide.
