溴化十六烷基三甲基铵与牛血清白蛋白相互作用的红外光谱研究

FT-IR Study of the Interaction between Bovine Serum Albumins and Cetyltrimethyl Ammonium Bromide

用二维红外相关分析方法研究了溴化十六烷基三甲基铵和牛血清蛋白间的相互作用.结果表明,在溴化十六烷基三甲基铵的存在下,牛血清蛋白的二级结构发生了变化;随着溴化十六烷基三甲基铵的增加,其变化的先后顺序为:β-转角、β-折叠、α-螺旋.

The means of the structures of the changing interaction of bovine serum albumins with cetyltrimethyl two-dimensional infrared correlation spectroscopy. The bovine serum albumins were changed when cetyltrimet sequence is β-sheet, β-strand, α-helix with the increase hyl of ammonium bromide was studied b results showed that the secondar ammonium bromide was added an cetyltrimethyl ammonium bromide y y d
