Abstract

Human gallstones were immersed with chloroform, ethanol and ether. The insoluble components were studied by normal Raman (SER) and FT-infrared (IR) spectroscopy. The results show that bilirubinate salts and proteins are the main components in the insoluble materials of gallstones. The secondary structure of the proteins in gallstones are dominated by (alpha) -helix structure. The results suggest that proteins play a key role in the formation of gallstones.
