title: High resolution mass spectra of malformin and related cyclic peptides.
abstract: A comparison of the high resolution mass spectra of synthetic and natural preparations of malformin provided new evidence for the revised structure: (see article): The interpretation of the mass spectra was aided by the examination of the spectra of the synthetic peptides, desthiomalformin and enantio-5-valine malformin.
