✦ Synopsis

In this paper, we have shown that it is possible to differentiate an aspartic acid residue from its p-aspartic acid isomer in dipeptides according to the characteristic fragmentation pathways, i.e. specific immonium ion formation and cleavages involving side-chain atoms.

The time-course of the HO-induced peroxidation of soybean phosphatidylcholine (PC) liposomes was monitored over 24 h by UV spectroscopy ( A 233 nm) and by fast-atom bombardment (FAB)-MS (positive-ion mode) and FAB-tandem (mass spectrometry) techniques. At the peak of maximal oxidation, a diagnostic

The observed fragmentations in collisionally activated dissociation (CAD) spectra of CX' adduct ions formed in the fast atom bombardment (FAB) mass spectra of C2'2X-bisammonium salts are the same as those previously put forward to account for the FAB mass spectra of these compounds. Thus, substituti
