In this paper, the surface enhanced Raman scattering (SERS) spectra of bilirubin-metal ion (Cu2+, Co2+, Zn2+, Cd2+) complexes (MBR) are reported.Abstract:
Surface-Enhanced Raman Scattering (SERS) spectra of bilirubin–metal ion (Cu2+, Co2+, Zn2+, Cd2+) complexes (MBR) are reported. These spectra reveal significant differences between MBR and bilirubin (BR) itself. But SERS spectra of bilirubin–Cu2+, Co2+, Zn2+, Cd2+ complexes are similar to each other. The mole ratio of bilirubin-metal in the complexes M2+ : BR = 1 : 1 was measured. Empirical assignments of the major SERS bands are given. The spectrum of CuBR in solution is consistent with a square planar structure. It should be noted, however, that H2O or COOH of another BR molecule occupy the positions above and below the plane in solutions of complexes of this type and forms CuO bond.
By comparing the SERS spectra of bilirubin-copper (or zinc) and biliverdin-copper (or zinc) complexes, the similar Raman frequencies and relative intensities were attributed to the oxidation of the bilirubin-copper (or zinc) complex to the green biliverdin-copper (Zn) complexes. It is shown that . © 1995 John Wiley & Sons, Inc.read more

TL;DR: The biological effects of the stable BV metallocomplex containing a delocalized unpaired electron should be further examined, and may provide an answer to the long-standing question of high energy investment in the catabolism of BV, which represents a relatively harmless molecule per se.

TL;DR: The Raman evidence suggests that in the bilirubin dianion/liposome complex the intramolecular hydrogen bonds between the propionate groups and the lactam NH/CO are ruptured and it is proposed that in this complex the bilIRubin propionates form ion pairs with the quaternary ammonium ion of the choline moiety of sphingomyelin.
