Abstract

The structure and properties of the aqueous proton is of fundamental interest in many areas of chemistry and biology. Acids and bases are molecules that are able to transfer (donate / accept) a proton according to Brønsted and Lowry, a process that was further explained by Lewis in terms of changes in their electronic structure in an attempt to offer a generalization of the Arrhenius theory. Simple proton transfers or the ones coupled to an electron transfer determine speciation, valence and reactivity in aqueous media and explain electrochemical processes, while voltage-gated proton channels have severe implications to the function of a number of tissues and species.
