Abstract
Conventional oxidative stress markers, including malondialdehyde and 1-Nonanol are derived from the oxidation of unsaturated fatty acids. Lipid-derivers free radicals have been studied to cause damages to bio membranes, proteins and other biomolecules. In addition, decompositions of lipid hydroperoxides are known to release excited triplet states of biomolecules composed with carbonyl groups. On the other hand, ultra-weak photon emissions (UPEs) are important to monitor in the redox status because UPEs have been used as biomarkers for non-invasive imaging techniques [1-3]. However, UPEs sometimes confuse oxidative stressors, because UPEs composed with various wave lengths. In this study, we investigated mechanisms of reactive species released from UPEs via chemical reactions of bio pigments (such as melanin) by qualitative analysis and polychromatic spectral pattern analysis.
