The analysis of peptides and proteins as well as the grander scope of proteomics (large
scale study of proteins) has been advanced by the development of a versatile array of ion …

Reversible phosphorylation is a key event in many biological processes and is therefore a
much studied phenomenon. The mass spectrometric (MS) analysis of phosphorylation is …

When non-mass spectrometrists are talking about mass spectrometry it rather often sounds
as if they were telling a story out of Poe's Tales of Mystery and Imagi-tion. Indeed, mass …

Natural or synthetic cyclic peptides often possess pronounced bioactivity. Their mass
spectrometric characterization is difficult due to the predominant occurrence of non …

This tutorial review describes the principles and practices of electron capture and transfer
dissociation (ECD/ETD or ExD) mass spectrometry (MS) employed for peptide and protein …

For about three decades, the chemistry of cation radicals derived from organic molecules
had received a major impetus from mass spectrometry. This was because cation radicals …

Although lipids are critical components of many cellular assemblies and biological
pathways, accurate descriptions of their molecular structures remain difficult to obtain. Many …

The effects of positive charge on the properties of ammonium and amide radicals were
investigated by ab initio and density functional theory calculations with the goal of …

Microorganisms comprise the bulk of biodiversity, but only a small fraction of this diversity
grows on artificial media. This phenomenon was noticed almost a century ago, repeatedly …

In recent years, electron capture (ECD) and electron transfer dissociation (ETD) have
emerged as two of the most useful methods in mass spectrometry‐based protein analysis …
