Discrimination among the four y-hydroxyornithine diastereomers was studied by fast atom bombardment mass spectrometry (FABMS). It is impossible to distinguish among the four diastereomers of this amino acid by positive-and negative-ion FAB and collisionally activated dissociation MS, but benzyloxyca
