Fluorescence quenching of tryptophan and related compounds by hydrogen peroxide.
The fluorescence of tryptophan and some related derivatives was found to be quenched by hydrogen peroxide. The quenching mechanism was shown to be essentially dynamic in nature, without any ground-state complex formation, and it is interpreted as resulting through an electron transfer from the excited indole ring to hydrogen peroxide.
