摘要: 本文在Bruker AM-500 NMR谱仪上,测试了河南桑蚕、辽宁柞蚕(黄茧和人工白茧)丝素在三氟乙酸溶液中的1H和13C NMR谱,归属了丝蛋白中主要氨基酸的NMR谱线。实验结果显示了桑、柞丝素中氨基酸含量的差异,但柞蚕黄茧和人工白茧丝素的NMR谱图相近。

Abstract: The 1H and 13C NMR spectra of fibroin from He Nan B. mori and Liao Ning A. pernyi (yellow and artificial white cocoon) in trifluoroacetic acid were recorded on Bruker AM-500 NMR spectrometer. The NMR spectral lines of main amino acid residues in silk protein have been obtained. The results show that the amount of amino acids in B. mori and A. pernyi is different, but the NMR spectrum of fibroin from A. pernyi yellow cocoon is similar to that of artificial white cocoon.
