蛛丝

To realize the molecular compositions and bio-spinning mechanisms of spidroin in spider major ampullate, the molecular weight and amino acid compositions of spidrion solution were measured and compared with that of dragline silk. The molecular conformations and morphologies of spidroin and dragline silk in different spinning phases were determined by circular dichroism spectroscopy and laser Raman spectroscopy.

本文以广泛分布于我国各地的大腹园蛛为对象，研究了大腹园蛛主腺体内丝蛋白溶液的分子量和氨基酸组成，并利用圆二色光谱和拉曼光谱分析了蜘蛛在不同成丝阶段丝蛋白的分子构象和聚集态结构的变化，以期了解蜘蛛主腺体内丝蛋白的分子组成及其生物纺丝机制。
