An improved scheme of leucine derivative fragmentation in mass spectrometry.

C Perier1, J Doumit, J Frey.   

Abstract

This study illustrates the contribution of stable isotopes to amino acid mass spectrometry. The mass spectra of natural leucine and 1(13)C leucine were compared and the mass fragmentography pattern analysed. This analysis indicates that the position of the stable isotope in tracer molecules should be very dependent on the analytical procedure used for their determination.
