| 摘 要： | 利用微分脉冲伏安法,研究了日落黄与牛血清白蛋白之间的相互作用.试验结果表明,日落黄与牛血清白蛋白之间形成近似1:1的复合物,从而造成日落黄峰电流的降低,两者之间的结合主要依靠静电力,且结合常数随温度升高而降低.研究有利于从分子水平上了解日落黄和牛血清白蛋白之间的结合作用,为更进一步了解日落黄的生物代谢机理提供一定的理论参考.

| Abstract: | The interaction between sunset yellow (SY) and bovine serum albumin (BSA) was studied by differential pulse voltammetry. The results showed that the decrease of peak current was caused by the formation of SY and BSA (approximately, 1:1)composite. The electrostatic force played the main role in their combination. The binding constant was decreased with increasing temperature. The research results are helpful in understanding the metabolism mechanism of SY and BSA at a molecular level, and provide some theoretical references for the study of the biological metabolism mechanism of SY. |
