Recent Chemistry and Biochemistry of Bile Pigments

This is the authors' abstract. We don't add key points for this paper.

Bile pigments are not merely waste products of the degradation of hemoglobin, but have specific functions in plants and lower animals, in which they occur in the form of chromoproteins (biliproteins). Chromic acid degradation under controlled conditions is particularly suitable for structural investigations. In the case of the phycobilins (bile pigments of red and blue algae), not only have the structures been established, but the linkages with the proteins have also been located.
