Abstract
Oxidative degradation of bovine serum albumin, a mixture of fluorescent amino acids tyrosine, tryptophan and phenylalanine and separately the same aromatic amino acids included in albumin, under the action of hydroxyl and hydroperoxyl radicals and UV radiationl = 253.7 nm was studied. The starting substances and reaction products were identified by fluorescence method in two-dimensional scanning mode. Stern-Folmer fluorescence quenching coefficients were calculated to analyze the results. Based on the Stern-Folmer coefficients, the reaction mechanisms of radicals and UV radiation with protein and individual amino acids are compared.
