采用激光显微拉曼光谱仪研究山羊绒、羊毛纤维的结构

Study on structures of cashmere and wool fibers by confocal laser raman microscopy

采用激光显微拉曼光谱技术对山羊绒、羊毛纤维的结构进行了研究 ,表明了该技术能有效、方便地相对定量比较和研究山羊绒、羊毛纤维的二硫键含量、蛋白质分子链的二级结构及聚集态结构等 ,指出山羊绒纤维胱氨酸二硫键含量低于羊毛 ,约为羊毛的 6 0 % ,而其大分子排列规整性高于羊毛 ,有序α

The contents of disulfide bonds and the secondary structures of cashmere and fine wool fibers are analyzed using Confocal Laser Raman Microscopy,concluding that the disulfide content of cashmere fiber is about 60% of that of fine wool and its degree of order in the secondary structure and its content of the ordered α-helix chains are higher than that of fine wool.
