What is/are true about bilirubin?
Conjugation is rate limiting step
Bilirubin has affinity for elastin
Conjugated bilirubin is maximum in blood
All
Ans. is 'b' i.e., Bilirubin has affinity for elastino Excretion of conjugated bilirubin into biliary canaliculi is the rate limiting step in bilirubin metabolism o Bilirubin has affinity for elastin, therefore jaundice is most easily seen in the sclera.o Normally unconjugated bilirubin is more than conjugated bilirubin, in bloodTotal bilirubin 0.3 -- 1.9 mg/dlConjugated bilirubin --> 0 to 0.3 mg/dlUnconjugated bilirubin --> Total - conjugated (0.3 -- 1.6 mg/dl)o Normally hemoglobin content of blood is between 120-160 gm/L (Harrison 17th/e p. A-2), and a normal adult usually have 5 litre of blood. So total hemoglobin is 600-800 gm.
