High-field 1H-n.m.r.-spectroscopic studies supported by chemical carbohydrate analyses show that skeletal keratan sulphates (KS-II) of bovine origin may be sub-classified into two groups. Keratan sulphate chains from articular and intervertebral-disc cartilage (KS-II-A) contain two structural features, namely alpha(1----3)-fucose and alpha(2----6)-linked N-acetyl-neuraminic acid residues, that are absent from keratan sulphates from tracheal or nasal-septum cartilage (KS-II-B).
化学碳水化合物分析支持的高场1H-核磁共振光谱研究表明,牛源的骨骼硫酸角质素(KS-II)可分为两组。来自关节和椎间盘软骨的硫酸角质素链(KS-II-A)包含两个结构特征,即α(1→3)-岩藻糖和α(2→6)连接的N-乙酰神经氨酸残基,而气管或鼻中隔软骨的硫酸角质素(KS-II-B)则没有这些特征。
