摘要
用Ｒａｍａｎ和ＦＴＩＲ光谱法研究了γ－球蛋白同银（Ｉ）离子的相互作用。结果表明，γ－球蛋白表面的氨基酸残基可同银（Ｉ）离子反应，生成２或４配位的物种，其振动光谱在酰胺带区域呈现明显差异。研究了在恒定的加热温度下不同反应时间对振动Ｒａｍａｎ光谱的影响。结果表明，Ｒａｍａｎ光谱强度在１５ｍｉｎ左右有最大值，当时间超过１５ｍｉｎ后。
The interaction for silver(Ⅰ)ion with γ globulin has been investigated by resonance spectroscopy.It is shown that 2 or 4 coordination species for amino acid residues of γ globulin with Ag(Ⅰ) ion were formed and their resonance spectra appear to be different in amide bands region.It has been studied that effect of reaction time on resonance Raman(RR) spectra in heat condition.Results showed that the intensity of RR has maximum at about 15 min of reaction,and after the time,Ag(Ⅰ) ion on species will reduced to elemental silver.
