This review covers the various synthetic routes to the carbocyclic and furanoid fatty acids, and examines numerous refinements to such schemes to improve the yield or to permit extension of the procedure to novel compounds. The occurrence of these unusual fatty acids in nature is also briefly ...
Isoprostanoids and isofuranoids are lipid mediators that can be formed from omega-3 and omega-6 polyunsaturated fatty acids (PUFAs). F2-isoprostanes formed from arachidonic acid, especially 15-F2t-isoprostane, are commonly measured in biological tissues for decades as the biomarker for oxidative ...
