Free radical oxidation (autoxidation) of alkenones and other lipids in cells of Emiliania huxleyi

Autoxidative damages were induced in cells of Emiliania huxleyi by culturing this strain under an atmosphere of air + 0.5% CO2. Several oxidation products of alkenones, sterols, monounsaturated fatty acids and chlorophyll phytyl side-chain could be detected after NaBH4 reduction and alkaline hydrolysis.
