Abstract

Quantum yields for pyridoxal, pyridoxamine, and pyridoxamine-5-phosphate at 25 degrees C in neutral aqueous solution were 0.048, 0.11, and 0.14, respectively. The fluorescence efficiencies were highly temperaturedependent, and the compounds were extremely sensitive to light. There were marked discrepancies between the values obtained in this study for quantum yield and fluorescence polarization of pyridoxamine-5-phosphate and the values recently reported by others.

摘要

在25摄氏度的中性水溶液中，吡哆醛、吡哆胺和磷酸吡哆胺的量子产率分别为0.048、0.11和0.14。荧光效率高度依赖于温度，并且这些化合物对光极其敏感。本研究中获得的磷酸吡哆胺的量子产率和荧光偏振值与其他人最近报道的值之间存在显著差异。
