Structural Identification of Glycopeptides Derived from Chicken Egg White Proteins [PDF]

Shipin Kexue
The primary proteins in chicken egg white are glycoproteins, which generate substantial glycopeptides in the digestive tract following gastrointestinal digestion. The structures of the glycopeptides have yet to be identified and elucidated. In this study,

Prediction of Intact N-Glycopeptide Retention Time Windows in Hydrophilic Interaction Liquid Chromatography

Molecules, 2022
Analysis of protein glycosylation is challenging due to micro- and macro-heterogeneity of the attached glycans. Hydrophilic interaction liquid chromatography (HILIC) is a mode of choice for separation of intact glycopeptides, which are inadequately ...
