摘要
用紫外、紫外二阶导数谱和FT IR光谱及曲线拟合等技术研究了水溶液中碳酸钙对牛血清白蛋白(BSA)微观结构的影响。结果表明 ,BSA的芳香族氨基酸残基受到干扰 ;二级结构也发生了变化。
The influence of calcium carbonate on the microstructure of bovine serum albumin (BSA) in aqueous solution was studied by ultraviolet spectrum and ultraviolet second order derivative spectrum and Fourier transform infrared spectrum.The results showed the changes of the microenvironment of the aromatic amino acid residues and secondary structure of BSA.It was the changes that provided a favorable condition for biomineral formation.
