Profiling of oxidized lipid products of marine fish under acute oxidative stress.

Free radical products including reactive oxygen species are potent to oxidize lipids and reliable measurements have been established mostly in human and rodent. To date, robust biomarkers were not used to assess the peroxidation in marine fish. The changes of oxidized lipid products from polyunsaturated fatty acids and cholesterol were assessed after exposure of H(2)O(2) to fish (medaka).
