The reaction between p-benzoquinone and H202 in slightly alkaline solutions yields three major quinoid products that accumulate in the reaction mixture: (a) 2.3-epoxy-pbenzoquinone, (b) 2-hydroxy-pbenzoquinone and (c) p-benzohydroquinone. The reaction is accompanied by photoemission, probably origin
The formation of electronically excited states during hydroperoxide metabolism is analysed in terms of recombination reactions involving secondary peroxyl radicals and scission of the 0-0 bond of peroxides by haemoproteins, mainly myoglobin. Both processes may be sequentially interrelated, for the c
