Abstract
Absorption of light converts bilirubin-IXalpha in solution to a mixture of what are probably cis-trans geometric isomers. This reaction is much faster than other photochemical reactions of bilirubin and reaches photoequilibrium before losses due to photooxidation are significant. At room temperature in the dark in the presence of trifluoroacetic acid or iodine or simply on standing, the photoproducts revert to the natural isomer. They also revert under visible light. Their formation and reversion can be followed by chromatography on polyamide and by absorbance difference spectroscopy.Entities:
