Abstract
The conversion of bilirubin into colourless products has been induced by transfer of electronic excitation energy and followed spectrophotometrically. The triplet excitation energy was generated by oxidation of 2-methylpropanal with oxygen in solution under catalytic action of human methemoglobin. A slower kinetics of transformation of bilirubin via this "photochemical reaction without light" has been observed for the bilirubin bound to human albumin as compared with the bilirubin alone.
