The Effect of Ultraviolet Radiation on Sulfhydryl and Disulfide Containing Amino Acids

Abstract

According to Rothman and his associates pigmentogenic stimuli, such as ultraviolet radiation, cause pigmentation by oxidizing or destroying inhibitory sulfhydryl compounds, thus enabling an enzyme to act on the pigment precursor. It was therefore of interest to study the effect of ultraviolet irradiation on the possible reduction of the -S-S- (disulfide) linkage of cystine and homocystine to -SH and possible oxidation of the -SH (sulfhydryl) group of cysteine to -S-S-. Methionine was also studied.
