Application of the thiobarbiturate assay to the measurement of lipid peroxidation products in microsomes.

By applying two different thiobarbiturate assay procedures in parallel to aliquots of a microsomal incubation mixture one can simultaneously monitor free malondialdehyde and malondialdehyde plus labile lipid peroxidation products. The levels of malondialdehyde increase continuously during the incubation of microsomes, NADPH and ferrous-ADP complex, while the lipid precursors of MDA stop forming when the system becomes depleted in NADPH. In contrast to systems in which lipids are undergoing autooxidation, NADPH-dependent lipid peroxidation does not appear to generate significant amounts of water-soluble malondialdehyde precursors. As a result, quantitative interpretation of results is straightforward in the microsomal system. In spite of the lack of specificity of the thiobarbiturate coupling reaction, interferences can be easily compensated for by using zero time controls.[1]
