Site-specific N-glycosylation of human chorionic gonadotrophin--structural analysis of glycopeptides by one- and two-dimensional 1H NMR spectroscopy.
Glycopeptides representing individual N-glycosylation sites of the heterodimeric glycoprotein hormone human chorionic gonadotrophin (hCG) were obtained from subunits hCG alpha (N-glycosylate
