Methods for determination of aldehydic lipid peroxidation products.
A complex pattern of aldehydes (alkanals, 2-alkenals, 2,4-alkadienals, 4-hydroxyalkenals) is generated by peroxidizing biological samples. Several methods based on HPLC or GC-MS have been developed to qualitatively and quantitatively measure the aldehydes in tissues, cells and cell fractions exposed to various pro-oxidative stimuli. 4-Hydroxynonenal, hexanal and propanal are, besides malonaldehyde, the most abundant aldehydes formed. The high sensitivity of the methods also allows the measurement of physiological aldehyde levels in plasma or low density lipoproteins and this could be of great importance for in vivo studies.
