Red cell metabolism. ø z dna possesses a more or less flat major grove. Hypoglycaemia can also be caused by disorders affecting the use of other fuels, such as those producing fatty acids and ketone bodies which are important alternative sources of energy. These include disorders resulting in predominantly unconjugated hyperbilirubinemia (Crigler-Najjar syndrome types I and II, and Gilbert syndrome) and those resulting in predominantly conjugated hyperbilirubinemia (Dubin-Johnson syndrome, Rotor syndrome, and benign recurrent intrahepatic cholestasis).
