ESR Spectrum Attributed to Trisulfide Neutral Radical [RSS(R)(SR)-R-center dot] of Protein Observed for alpha-Keratin Present in White Human Hair
ESR spectrum attributed to the trisulfide neutral radical of protein (RSS(R)(SR)-R-center dot, g(1) = 2.055, g(2) = 2.035, and g(3) = 2.000) is observed for the first time for a-keratin present in completely dried white human hair exposed to near-UV radiation under a helium atmosphere.
