Abstract
We proposed EPR spectroscopy using spin-trap DEPMPO as a novel method for the detection of a hydrogen atom (H-center dot) produced by chemical and biological systems. In complex EPR spectra of DEPMPO adducts in biological systems, spectral lines of unknown origin have been observed. We have assumed (Bacic, G.; Mojovic, M. Ann. N. Y. Acod. Sci. 2005, 1048, 230-243) that those lines represent the spectrum of a hydrogen atom (H-center dot) adduct i.e., DEPMPO/H. Ail electrochemical system known to produce only H-center dot radicals was used here in order to obtain a separate spectrum of the DEPMPO/H adduct. An acquired spectrum as well as a computer spectral simulation of the DEPMPO/H adduct showed considerable resemblance with additional lines in the EPR spectra of DEPMPO adducts in biological systems-plant plasma membranes and cell walls. This shows that such a radical is produced by plants as well as that DEPMPO is suitable for detection in both electrochemical and biological systems.
