1181por Koppenol, Willem H.“…The following considerations may help to guide experiments. (1) The standard Gibbs energy for the homolysis reaction RSNO → RS(•) + NO(•)(aq) is +110 ± 5 kJ mol(–1). (2) The electrode potential of the RSNO, H(+)/RSH, NO(•)(aq) couple is −0.20 ± 0.06 V at pH 7. (3) Thiol nitrosation by NO(2)(–) is favorable by 37 ± 5 kJ mol(–1) at pH 7. (4) N(2)O(3) is not involved in in vivo nitrosation mechanisms for thermodynamic — its formation from NO(2)(–) costs 59 kJ mol(–1) — or kinetic — the reaction being second-order in NO(2)(–) — reasons. (5) Hemoglobin (Hb) cannot catalyze formation of N(2)O(3), be it via the intermediacy of the reaction of Hb[FeNO(2)](2+) with NO(•) (+81 kJ mol(–1)) or reaction of Hb[FeNO](3+) with NO(2)(–) (+88 kJ mol(–1)). (6) Energetically and kinetically viable are nitrosations that involve HNO(2) or NO(•) in the presence of an electron acceptor with an electrode potential higher than −0.20 V. …”
