Abstract

Gas-phase ion/ion reactions are emerging as useful and flexible means for the manipulation and characterization of peptide and protein biopolymers. Acid/base-like chemical reactions (i.e., proton transfer reactions) and reduction/oxidation (redox) reactions (i.e., electron transfer reactions) represent relatively mature classes of gas-phase chemical reactions. Even so, especially in regards to redox chemistry, the widespread utility of these two types of chemistries is undergoing rapid growth and development. Additionally, a relatively new class of gas-phase ion/ion transformations is emerging which involves the selective formation of functional-group-specific covalent bonds. This feature details our current work and perspective on the developments and current capabilities of these three areas of ion/ion chemistry with an eye towards possible future directions of the field.

摘要

气相离子/离子反应正成为一种有用且灵活的手段,可用于操纵和表征肽和蛋白质生物聚合物。酸/碱样化学反应(即质子转移反应)和还原/氧化(氧化还原)反应(即电子转移反应)代表了相对成熟的气相化学反应类别。即便如此,特别是在氧化还原化学方面,这两种类型的化学物质的广泛应用正在迅速发展和壮大。此外,一种新的气相离子/离子转化类型正在出现,涉及到特定官能团共价键的选择性形成。本文详细介绍了我们目前在离子/离子化学这三个领域的工作和观点,以及该领域未来可能的发展方向。
