Previously, we identified four metabolites of (-)-epicatechin in blood and urine: (-)-epicatechin-3'-O-glucuronide (E3'G), 4'-O-methyl-(-)-epicatechin-3'-O-glucuronide (4'ME3'G), (-)-epicatechin-7-O-glucuronide (E7G), and 3'-O-methyl-(-)-epicatechin-7-O-glucuronide (3'ME7G) (Natsume et al. Free Radical Biol. Med. 34, 840-849, 2003). The aim of the current study was to compare the

Nitrogen-centered and β-carbon-centered hydrogen-deficient peptide radicals are considered to be intermediates in the matrix-assisted laser desorption/ionization in-source decay (MALDI-ISD)-induced Cα-C bond cleavage of peptide backbones when using an oxidizing matrix. To understand the general mechanism of Cα-C bond cleavage by

In in-source decay (ISD) in matrix-assisted laser desorption/ionization (MALDI)-mass spectrometry (MS), 1,5-diaminonaphthalene (1,5-DAN) is a most frequently used matrix probably due to the highly sensitive detection of fragment ions. 1,5-DAN is a reducing matrix generating c- and z-series ions by

Since its introduction in the 1980s, matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) has gained a prominent role in the analysis of high molecular weight biomolecules such as proteins, peptides, oligonucleotides, and polysaccharides. Its application to low molecular weight compounds
