Part Descriptions

LP15365-7   Alpha ketoglutarate
2-Ketoglutaric acid (alpha ketoglutarate) is an important nitrogen transporter and a key intermediate in the Krebs cycle.Amino groups of amino acids are attached to it by transamination and carried to the liver where the urea cycle takes place. Increased levels found with 2-ketoglutaric DH deficiency, GA I, 2-amino/2-ketoadipate acidemia, dihdrolipoyl DH(E3) deficiency, glycogen storage disorders I, 2-hydroxyglutaric aciduria(D-form), and fumarase deficiency. Very low values are sometimes encountered in chronic fatigue syndrome.(Information from: Kumps A, Duez P, Mardens Y.

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.
