Fragmentation behavior of glycated peptides derived from D-glucose, D-fructose and D-ribose in tandem mass spectrometry.

Abstract

Nonenzymatic glycosylation (or glycation) is a common nonenzymatic side-chain specific sequence-independent posttranslational modification formed by the reaction of reducing carbohydrates with free amino groups. Thus, proteins can react with aldoses or ketoses to yield Amadori or Heynes compounds, respectively. Here, the fragmentation behavior of D-glucose… (More)
