Identification of leucine, isoleucine and norleucine in the positive ion FAB spectra of peptides

Wigger Heerma, Erich R. Bathelt

Abstract

Application of a recently published criterion to discriminate between leucine and isoleucine demonstrated the simplicity and usefulness of the method. The criterion has been extended with data from norleucine. Unimolecular decompositions can also be used to characterize the identity of the amino acids.
