title: [The effect of the charge of aromatic amino acid, peptide and protein molecules on the rate of radical formation during UV-irradiation].
abstract: It has been shown that the rate of radical formation under UV-irradiation of some aromatic amino acids, peptides and proteins abruptly increases with pH rise in the region 9.5-11. This effect is observed only in the case when the total charge of the molecule after ionization remains negative.
