General description

Bilirubin is an orange-yellow bile pigment and one of the major end products of hemoglobin decomposition. It contains conjugated double bonds and reactive hydrogen atoms. In adults, the upper limit of the normal range of bilirubin is >1mg/dL. Serum levels of bilirubin in healthy newborns are less than 15 mg/dl. This product corresponds to the unconjugated form.

Biochem/physiol Actions

Bilirubin is reported to cross the blood-brain barrier and exert significant antioxidant effects in the brain. This pigment aids in coloration in the various forms of jaundice. Bilirubin levels act as biomarkers in liver and blood disorders. Unconjugated form of bilirubin at lower levels serves as a physiological antioxidant. However, increased concentration of bilirubin is toxic and leads to neonatal hyperbilirubinemia in neonates.

Reconstitution

Unstable in basic solutions; reconstitute just prior to use.

The reaction of magnesium or zinc amides with alkyl or benzyl halides is an attractive approach to make C-N bonds, especially for electron-poor organic halides. The magnesium-promoted preparation of hindered non-nucleophilic amine (N,N-diisopropylethylamine) from ethyl chloride and zinc diisopropylamide has

Bilirubin, the end product of heme catabolism in mammals, is generally regarded as a potentially cytotoxic, lipid-soluble waste product that needs to be excreted. However, it is here that bilirubin, at micromolar concentrations in vitro, efficiently scavenges peroxyl radicals generated
