摘要
在生命体系内正铁色素具有摄铁和输铁的功能,人工合成的模拟化合物具备了正铁色素的主要功能基团和相近的性质.本工作利用铁(Ⅲ)离子的顺磁性质,测定不同铁(Ⅲ)离子浓度下模拟正铁色素的诱导弛豫时间,根据简化了的Solomon—B1oemoergen公式,计算出铁(Ⅲ)离子到所有被测质子(即氢原子)的相对距离,比较清楚地得到模拟正铁色素在溶液中的构象。
The ferrichrome analogues mainly have the same function as natural ones. In this work, the relaxation times of the ferrichrome analogue B2 at different Fe(Ⅲ) concentrations have been measured, and the relative distances from Fe(Ⅲ) ion to all the protons have been also worked out by using a simplified solomon-Bloembergen equation. The conformation of this complex in CDC13 solution can be imagined out.
