ZZ-Bilirubin undergoes photoisomerization to configurational (ZE and EZ isomers) and structural (LR) isomers in buffered aqueous solution containing serum albumins. The efficiency and the course of the isomerization are very much dependent on the mammals from which serum albumins are taken.
在含有血清白蛋白的缓冲水溶液中,ZZ-胆红素会发生光异构化,生成构型异构体(ZE 和 EZ 异构体)和结构异构体(LR 异构体)。异构化的效率和过程在很大程度上取决于提取血清白蛋白的哺乳动物。

The quantum yields of the isomerization and photostationary state isomer ratios of the photoisomerization of (4Z,15Z)-bilirubin IXα (ZZ-BR) were determined in an aqueous buffered solution in the presence of human serum albumin (HSA) at a molar ratio of [ZZ-BR]/[HSA] from 0.5 to 2. The BR isomer compositions in the photostationary state were constant at [BR]/[HSA] = 0.5—0.7. With increasing [ZZ-BR]/[HSA]
