摘要: 用波谱分析结合酶法谱推测猪喉软骨硫酸软骨素包含GlcA(β1-3)GalNAc4SO3、GlcA(β1-3)GalNAc6SO3重复结构单元,不存在GlcA2SO3(β1-3)GalNAc4SO3、GlcA2SO3(β1-3)GalNAc6SO3(硫酸皮肤素特征)和NeuAc(α2-3)Gal(β1-4)GlcNAc4SO3(硫酸角质素特征)重复结构单元。

Abstract: The results of enzyme and spectra analyse indicated that the ChS digested from pig laryngeal cartilage contains the repeated structure units of GlcA(β1-3)GalNAc4SO3 and GlcA(β1-3)GalNAc6SO3, it may not have the structure characteristics of keratan sulfate and dermatan sulfate such as NeuAc(α2-3)Gal(β1-4) GlcNAc4SO3 units and GlcA2SO3(β1-3) GalNAc4SO3, GlcA2SO3(β1-3) GalNAc6SO3 untis.
