Structure of ascorbic acid and its biological function. I. ESR determination of the ascorbyl radical in biological samples and in model systems. 抗坏血酸的结构及其生物学功能。生物样品和模型系统中抗坏血酸自由基的ESR测定。

ESR investigations on lyophilized systems have shown that the signal at g = 2.005 can be explained by an interaction between Na+ or K+ and the anionic ascorbyl radical. The unpaired electron is probably localized near the C(4) region and is produced by a cleavage of an H atom belonging to a water molecule bound tightly to C(4). Experiments on aqueous samples revealed that ascorbic acid in its radical configuration and in its highest concentration exists only at physiological pH and temperature. An additional splitting is obtained by the ring formation between C(3) and C(6)-OH. The coupling constants of the triplets produced by the CH2-6 protons differ between ascorbic acid and isoascorbic acid. Thus, the ESR technique can be applied for an easy distinction between these two epimers.

冻干体系的ESR研究表明，g = 2.005处的信号可以用Na+或K+与阴离子抗坏血酸自由基的相互作用来解释。未配对电子可能定位在C(4)区附近，是由与C(4)紧密结合的水分子中的H原子裂解产生的。对水样品的实验表明，抗坏血酸的自由基构型和最高浓度只存在于生理pH值和温度下。通过在C(3)和C(6)-OH之间形成环，获得了额外的分裂。抗坏血酸和异抗坏血酸的CH2-6质子产生的三联体偶联常数不同。因此，ESR技术可以很容易地区分这两个外显子。
