Proton affinities of the 20 common .alpha.-amino acids

Proton affinities of the 20 common .alpha.-amino acids

We report the first measurement of the gas-phase basicities (- Delta G of protonation) of all of the 20 common alpha -amino acids, from which we can derive their proton affinities (- Delta H of protonation).
