LP18407-4   2-Oxo,3-Methylvalerate
3-Methyl-2-oxovaleric acid is a metabolite of isoleucine in man, animals and bacteria. It is the alpha-keto acid analogue of isoleucine. 3-Methyl-2-oxovaleric acid is produced from isoleucine by cytosolic branched chain aminotransferase 1 (EC:, whereupon it is further degraded by branched chain keto acid dehydrogenase E1 to 2-Methyl-1-hydroxybutyl-ThPP. It is used as a clinical marker for maple syrup urine disease (MSUD). MSUD is caused by a deficiency of the branched-chain -keto acid dehydrogenase compex resulting in an accumulation of branched-chain amino acids and the corresponding -keto-and -hydroxy acids in blood, urine and cerebrospinal fluid causing neurological damage and mental retardation.

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
