This product mainly comes from the reduction product of heme in the aging red blood cell after disintegrating through a series of catabolism. For golden or deep red brown monoclinic crystal, odorless tasteless. Soluble in benzene,  carbon disulfide and other organic solvents; It can also be dissolved in a hot mixture of ethanol . Sodium salts are soluble in water, but calcium salts, magnesium salts and barium salts are insoluble in water. Dry solid is more stable; solution in the dark is also more stable; It is unstable in lye (such as 0.1mmol/L ) or in the presence of ferric ions and is quickly oxidized to biliverdin, which can be reduced to bilirubin by in vitro chemical reactions or biliverdin reductase. Bilirubin can bind to Chemicalbook glycine, alanine, or histidine. Bilirubin is a strong endogenous antioxidant in normal serum concentrations. The molecular structure of bilirubin can be ketone type and alcohol type. Due to the specific curly structure of bilirubin, the hydrophobicity of bilirubin is increased and it can enter the lipid molecule. Bilirubin has an extended conjugated double bond system and active hydrogen atoms that prevent oxidation. The results show that bilirubin can inhibit the oxidative modification of LDL(low density lipoprotein in blood) to a certain extent in vitro, which can inhibit and alleviate the formation of atherosclerosis caused by oxidative modification of LDL, and finally achieve the purpose of prevention and treatment of coronary heart disease.

     1.Bilirubin has a variety of pharmacological effects and is the main raw material of artificial bezoar. Pharmacological experiments have proved that it has a good inhibitory effect on W256 tumor, and the inactivation rate and inhibition index of Japanese encephalitis virus are 1-1.5 times higher than deoxycholic acid and cholic acid. It also Chemicalbook is an effective treatment of liver diseases, in the case of liver tissue is not damaged, there is the role of proliferation of new cells, can treat serum hepatitis, cirrhosis and other diseases, in addition, bilirubin has sedation, shock, antipyretic, antihypertensive, promote red blood cell regeneration and other effects.
     2.Used for determination of bilirubin in artificial bezoar, preparation and biochemical study of artificial bezoar.
     3.Bilirubin has a variety of pharmacological effects and is the main raw material of artificial bezoar. Pharmacological experiments showed that it had a good inhibitory effect on W256 tumor, and the inactivation rate and inhibition index of Japanese encephalitis virus were 1 ~ 1.5 times higher than deoxycholic acid and cholic acid. It is also Chemicalbook is an effective treatment of liver diseases, in the case of liver tissue is not damaged, has the effect of proliferation of new cells, can treat serum hepatitis, cirrhosis and other diseases, in addition, bilirubin has sedation, shock, antipyretic, antihypertensive. Promote red blood cells and other functions.
     4.Biochemical research. Analytical chemistry. Biochemical research. Synthetic bezoar. An antioxidant that protects the membrane phospholipids from oxidation by free radicals. Even at nanomolar concentrations, neurons are protected from oxidative damage.
     5.A major component in the decomposition of heme; The principal pigment of bile; Acts as an antioxidant and an effective based scavenger, protecting cell membrane lipids from the oxidation of these active groups.
     6.An antioxidant that protects the membrane phospholipids from oxidation by  free radicals.
