FT IR STUDY ON THE SOLID STATE REACTION OF BILIRUBIN ON BaF 2 |
| |
Abstract: | Bilirubinate complexes are the main component of pigment gallstones and the recent researches suggested that bilirubin free radical plays a role in some biological processes.In this paper the solid state reaction of bilirubin on BaF 2 was examined by FT IR.The solid state reaction was produced by grinding the crystalline bilirubin and single crystals BaF 2 together in an agate mortar.From the results the free radical mechanism is suggested in the solid state reaction of bilirubin on BaF 2.The replacement of H on NH of pyrrole by Ba 2+ was prior to that of H on COOH.The sturcture of the resultant complex from the solid state reaction is different compared with that from the liquid state reaction. |
