Abstract
The 360-MHz proton magnetic resonance spectra of 2-acetamido-1-N-(4-l-aspartyl)- 2-deoxy-beta-d-glucopyranosylamine (GlcNAc beta1-> Asn) and 2-acetamido-6-O-(alpha-l-fucopyranosyl)-1-N -(4-l-aspartyl)-2-deoxy-beta-d-glucopyranosylamine (Fuc1-> 6GlcNAc1 Asn) in deuterium oxide were completely interpreted. The chemical shifts and coupling constants were refined by simulation of the spectra. By means of an adapted Karplus equation the pyranose ring
