Paper Abstract

Since calcium bilirubinate (CaBR) and its acid salt (CaHBR) were considered to be the main components of human pigment gallstone, these compounds were synthesized and investigated chemically, crystallographically and spectroscopically by several authors. In recent years, we found that the chemical compositions of these compounds varied from sample to sample, and the protonated carboxyl group of these samples was much more reactive than for bilirubin. It resembles the characteristics of human pigment gallstone. In order to enhance our understanding of the structure of gallstone, an investigation on the composition and coordination of calcium bilirubinate has been carried out. A series of CaHBR samples were prepared by reacting diluted pyridine solutions of bilirubin and
