Antifreeze glycopeptide diastereomers [PDF]

Beilstein Journal of Organic Chemistry, 2012
Antifreeze glycopeptides (AFGPs) are a special class of biological antifreeze agents, which possess the property to inhibit ice growth in the body fluids of arctic and antarctic fish and, thus, enable life under these harsh conditions. AFGPs are composed

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

Preparation and Evaluation of New Glycopeptides Obtained by Proteolysis from Corn Gluten Meal Followed by Transglutaminase-Induced Glycosylation with Glucosamine

Foods, 2020
New glycopeptides were generated by proteolysis from corn gluten meal (CGM) followed by transglutaminase (TGase)-induced glycosylation with glucosamine (GlcN). The glycopeptides exhibited desirable antioxidant and intracellular ROS-scavenging properties.
