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.

Characteristics of electrospray ionization mass spectrometry/collision-induced dissociation (ESIMS/CID) mass spectra of microcystins, cyanobacterial cyclic heptapeptide hepatoxins, were examined. The collision conditions showed remarkable e †ects on the quality of the CID mass spectra, which were di
Recombinant Factor VIII (rFVIII) is involved in the cascade of biochemical reactions leading to blood coagulation and is used for the treatment of haemophilia A. Plasma-derived FVIII (pdFVIII) has been reported to be post-translationally modified by sulfation of tyrosine residues at positions 346, 1
