title: Fast-atom bombardment mass spectra of some pentapeptides related to natural enkephalins.
abstract: The mass spectral features of four diastereoisomeric pairs of peptides related to the enkephalins recorded under fast-atom bombardment conditions are presented and shown to provide evidence of molecular weight and amino acid content and sequence.
