A quantum chemical substantiation of the intermediate (thiyl radical) nature and reaction regioselectivity (S,S-coupling) of the L-cysteine homolytic oxidative dimerization resulting by the L-cystine formation has been carried out. The electrostatic factor does not prevent the reaction occurrence.
Предпринято квантовохимическое обоснование природы интермедиата (тиильный радикал) и региоселективности (S,S-сочетание) реакции гомолитической окислительной димеризации L-цистеина с образованием L-цистина. Протеканию реакции не препятствует электростатический фактор.
