## Abstract **Most proteins in proteomics** are identified from tandem mass spectra of doubly protonated tryptic peptides. Statistical studies indicate that these spectra fall into two distinct classes. IR spectroscopy experiments and DFT calculations performed on model __b__~2~ ions show that pept

## Abstract Gas phase fragmentation of peptideโderived Amadori products was investigated using synthetic compounds regioselectively deuterated as well as labeled with ^18^O at aminofructose moiety. The eliminated molecule CH~2~O contains exclusively protons attached to carbon C6 of the aminofructos
Dermorphin (Tyr-DAla-Phe-Gly-Tyr-Prder-NH2), a potent natural peptide opioid, its synthetic L-Ala\* analog, and all the N fragments from the tripeptide (Tyr--DAla-Phe-NH,) to the parent hexapeptide amide were characterized for the first time by means of proton nmr spectroscopy at 11.74 T. Assignmen
Natural-abundance 13C T1 and NOE measurements have been made for backbone and side-chain sites in peptide fragments of transthyretin (TTR 10-20, TTR 105-115, and TTR 105-115Met111) at 13C Larmor frequencies of 125 and 75 MHz. These peptides have previously been implicated in the formation of amyloid
