Translated from Bioorganicheskaya Chimiya, Vol. A. Ovchinnikov Institute of Bioorganic Chemistry, Russian Academy of Sciences. Short irradiation of an aqueous solution of Gly by an ultraweak source of UV photons initiates a process accompanied by the accumulation of ammonia ions.
More intense deamination occurs in an aqueous solution in the presence of hydrogen peroxide.
The kinetics of ammonia formation coincides with the kinetics of enhancement of luminescence, that was registered in the presence of a luminofore, ethidium bromide or Tyr. If the luminofore concentration exceeds the optimum, the reaction rate enhancement deccelerates and the ammonia yield decreases. UV photons generated in the reaction system after the process initiation supposedly play a significant role in the process development and reaction chain branching.
