Arachidonic Acid Pathway
The arachidonic acid pathway describes the biosynthesis of eicosanoids from arachidonic acid (AA) including its formation from omega-6 polyunsaturated fatty acids (PUFAs) and the synthesis of eicosanoids from eicosapentaenoic acid (EPA) including its formation from omega-3 PUFAs. Eicosanoids are short-lived biologically potent, autocrine or paracrine acting, lipid signaling molecules.
The AA pathway is involved in many physiological processes including inflammationand cancer. The pleiotropic effects of modulating this pathway are manifold and are depending on the levels of fatty acids from (dietary) substrates, which in turn modulate the level of eicosanoid precursors (AA and EPA) determining the amounts of eicosanoid lipid mediators actually produced. Initial and still ongoing research on the pharmacological inhibition of inflammatory reactions by nonsteroidal antiinflammatory drugs...
