The influence of the antioxidant spermine of the UV-induced formation of free radicals from tryptophan in frozen aqueous solutions was studied by electron paramagnetic resonance (EPR) instrumentation, and the stability of the radicals was investigated in the range 95-200 K. Without spermine, the try
