The complete 1H- and 13C-n.m.r. assignments for beta-D-Galp-(1----4)-beta-D-GlcpNAc-6-SO3H-(1----6)-[beta-D-Galp-(1----3 )]- D-GalNAcol and alpha-NeuAcp-(2----3)-beta-D-Galp-(1----3)-[beta-D-Galp-(1----4)-b eta-D- GlcpNAc-6-SO3H-(1----6)]-D-GalNAcol were made by a combination of 2-D correlation experiments (Relayed-Cosy; and 13C,1H Correlation-shift n.m.r. spectroscopy), and 1-D n.m.r. spectroscopy. The results illustrate the ability of these methods to locate sulphate and NeuAc groups in anionic mucinous glycoproteins.
通过二维相关实验（接力相关谱；以及碳-13、氢-1 相关位移核磁共振光谱）和一维核磁共振光谱相结合的方法，完成了对β-D-吡喃半乳糖-(1→4)-β-D-吡喃葡萄糖胺-6-磺酸-(1→6)-[β-D-吡喃半乳糖-(1→3)]-D-半乳糖胺醇以及α-唾液酸-(2→3)-β-D-吡喃半乳糖-(1→3)-[β-D-吡喃半乳糖-(1→4)-β-D-吡喃葡萄糖胺-6-磺酸-(1→6)]-D-半乳糖胺醇的完整氢-1 和碳-13 核磁共振归属。结果表明这些方法能够在阴离子黏液糖蛋白中定位硫酸根和唾液酸基团。
