Abstract

The results of an experimental study of UV absorption and luminescence of an aqueous solution of coenzymes NAD (NADH) and NADP (NADPH) triphosphate at ambient conditions are presented. High-temperature fluorescence is caused by two different optical centers, belonging to adenine and nicotinamide aromatic systems. The spatial form of coenzyme molecules is modeled by quantum-mechanics calculations, and the mechanism of such fluorescence is proposed and discussed.

了解NAD+(NADH)和NADP+(NADPH)水溶液高温荧光的机理

摘要

介绍了在环境条件下辅酶 NAD (NADH) 和 NADP (NADPH) 三磷酸水溶液的紫外线吸收和发光的实验研究结果。高温荧光由两个不同的光学中心引起，分别属于腺嘌呤和烟酰胺芳香系统。辅酶分子的空间形式通过量子力学计算建模，并提出并讨论了这种荧光的机制。
