许多(如果不是大多数的话)氧化还原反应与质子转移偶联。这包括最常见的化学势能来源,从为电池提供动力的生物能过程到为汽车提供动力的化石燃料燃烧。这些质子偶联电子转移或PCET过程可以涉及多个电子和多个质子,如在分子氧(O2)到水的4 e-,4 H+还原(等式1)中,或者可以涉及一个电子和一个质子,如在酶催化中从酪氨酸残基(TyrOH)形成酪氨酰基自由基(等式2)。多质子过程以单电子和单质子步骤进行。在单电子步骤中进行的有机反应涉及自由基中间体,其在广泛的化学,生物和工业过程中起着关键作用。这一广泛而多样的PCET反应是许多化学和生物化学过程的核心,从生物催化和能量转换,到大宗工业化学品,
Many, if not most, redox reactions are coupled to proton transfers. This includes most common sources of chemical potential energy, from the bioenergetic processes that power cells to the fossil fuel combustion that powers cars. These proton-coupled electron transfer or PCET processes may involve multiple electrons and multiple protons, as in the 4e-, 4H+ reduction of dioxygen (O2) to water (eq 1), or can involve one electron and one proton such as the formation of tyrosyl radicals from tyrosine residues (TyrOH) in enzymatic catalysis (eq 2).In addition, many multielectron, multiproton processes proceed in one-electron and one-proton steps. Organic reactions that proceed in one-electron steps involve radical intermediates, which play critical roles in a wide range of chemical, biological, and industrial processes. This broad and diverse class of PCET reactions are central to a great many chemical and biochemical processes, from biological catalysis and energy transduction, to bulk industrial chemical
