摘要
本文报导血红蛋白(Hb)同银(Ⅰ)-铜(Ⅱ)离子的作用.研究表明,在pH10.5的B5O72--OH-缓冲介质中,当有十二烷基硫酸钠(SDS)和甲醛存在时,Hb-Ag-Cu物种表现出强的橙黄色,用FT-IR、UV/VIS和振动Raman光谱研究了Hb-Ag-Cu物种的形成机理.表明血红蛋白中氨基酸残基上的氮和氧与银-铜离子有较强的作用,对Hb中氨基的修饰证明了这一机理。
The interaction on hemoglobin (Hb) with silver(I)-copper (II) ions have been developmented byFT-IR,UV /VIS,Raman spectroscopies. It's shown that the Hb-Ag-Cu species are appear to strongerorange-yellow colour when sodium dodecyl sulphate (SDS) and formaldehyde have presence and thepH 10. 2 range of B4O72--OH- buffer. It is forming a sensitive species that the silver and copper ionswith nitrogen and oxygen atums of residues of amino acid in Hb. The mechanism was proved that bymodification of amino groups.
