Chiral recognition of amino acids by electrospray ionisation mass spectrometry/mass spectrometry

Abstract

Chiral recognition of 19 common amino acids is achieved by investigating the collision-induced dissociation spectra of protonated trimers formed by electrospray ionisation of amino acids in the presence of one of the following chiral selectors: L- and D-N-tert-butoxycarbonylphenylalanine (BPhe), L- and D-N-tert-butoxycarbonylproline (BPro) and L- and D-N-tert-butoxycarbonyl-O-benzylserine (BBSer).
