Kinetics of the photochemical interconversion among geometric photoisomers of bilirubin.

K Isobe, S Onishi.   

Abstract

Kinetic study of the photochemical interconversion of three geometric photoisomers of bilirubin, namely peaks 1, 2 and 3, under anaerobic conditions was performed by using high-pressure liquid chromatography. Rapid and definite interconversion among these three peaks and the parent pigment occurred on radiation by blue light.
