Definition and causes of jaundice Jaundice (icterus) refers to the yellow color of the skin, nail beds, and sclerae caused by deposition of bilirubin, secondary to increased bilirubin levels in the blood. There are three major forms of jaundice hemolytic jaundice, caused by massive lysis of red blood cells, releasing more heme than can be handled by the reticuloendothelial system obstructive jaundice, resulting from obstruction of the bile duct and hepatocellular jaundice, caused by damage to liver cells that decreases the liver s ability to take up and conjugate bilirubin. In addition, neonatal jaundice is caused by the low activity of hepatic glucuronylation of bilirubin, especially in premature infants. 

The synthesis of unsymmetrical 1,4-diketones results from the conjugate addition of the nitronate anion (as the acyl anion equivalent) to an a,fi-unsaturated ketone [Method (6)].l47a The intermediate nitroketone is converted into the diketone by reduction with titanium(m) chloride at pH 1, or by ozono-lysis of the nitronate anion147b (cf. Section 5.7.7, p. 599). 

B. Increased lysis of red blood cells causes bilirubin to be elevated in the blood. The liver conjugates the bilirubin and excretes it into the gut where it is converted to stercobilin.
