Abstract
THERE is now a substantial, if not altogether unambiguous, body of evidence that the mode of charge migration in certain proteins1–5 and carbohydrates6,7 is predominantly protonic and similar, in certain respects, to that occurring in ice2 and potassium dihydrogen phosphate8. The mechanism is, in essence, reminiscent of the familiar9 Grotthuss process in which there is a systematic switching, or translational jumping of the protons within the intermolecular (that is, external) hydrogen bonds.
