Antioxidant and Alcohol Dehydrogenase Activating Activities of Corn Glycopeptide by Ultrafiltration Membrane Classification

Shipin gongye ke-ji, 2022
In the present work, corn peptides from zein were modified by D-glucosamine under transglutaminase to produce corn glycopeptides, and then the corn glycopeptides were fractionated sequentially using ultrafiltration membranes with molecular weight cut-off

Identification, mapping and relative quantitation of SARS-CoV-2 Spike glycopeptides by Mass-Retention Time Fingerprinting

Communications Biology, 2021
Mapping multiple glycan species to the same peptide and location from shared retention time of glycopeptides with MS and HPLC, Chalk, Greenland et al. construct a detailed mass-retention time database for Spike protein glycopeptides. This allows any mass

Fragmentation characteristics of glycopeptides [PDF]

, 2013
Mass spectrometric analysis of glycopeptides is an emerging strategy for analysis of glycosylation patterns. Here we present an approach using energy resolved collision induced decomposition (CID) spectra to determine structural features of glycopeptides.
