Biochem/physiol Actions

3,4-Dihydroxybutyric acid is a normal human urinary metabolite that is excreted in increased concentration in patients with succinic semialdehyde dehydro- genase (SSADH) deficiency, while healthy adults excrete 0.37 +/- 0.15 (SD) mmoles of 3,4- dihydroxybutyrate per 24 hr. The renal clearance of this compound is roughly equal that of creatinine. This metabolite is also detectable in blood.

We describe the rapid and sensitive detection of 4-hydroxybutyric acid, which is a marker compound for succinic semialdehyde dehydrogenase (SSADH) deficiency. Urinary 4-hydroxybutyric acid and 3,4-dihydroxybutyric acid were targeted, quantified by gas chromatography-mass spectrometry after simplified urease digestion in which

Lesch-Nyhan syndrome (LNS) is caused by a severe deficiency of hypoxanthine-guanine phosphoribosyltransferase (HPRT) and clinically characterized by self-injurious behavior and nephrolithiasis; the latter is treatable with allopurinol, an inhibitor of xanthine oxidase which converts xanthine and hypoxanthine into uric acid.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
