Urinary 4-hydroxy-3-methoxymandelic (vanillylmandelic) acid, 4-hydroxy-3-methoxyphenylacetic (homovanillic) acid, and 5-hydroxy-3-indoleacetic acid determined by liquid chromatography with electrochemical detection.
We describe a simple liquid-chromatographic assay of urinary 4-hydroxy-3-methoxymandelic (vanillylmandelic) acid, 4-hydroxy-3-methoxyphenylacetic (homovanillic) acid, and 5-hydroxy-3-indoleacetic acid with electrochemical detection, with direct injection of the sample. The first two analytes are measured simultaneously; 5-hydroxy-3-indoleacetic acid is measured separately. Chromatographic condi...
متن کاملBacterial metabolism of 3-hydroxy-3-methylglutaric acid.
An organism belonging to Pseudomonadaceae and capable of utilizing 3-hydroxy-3-methylglutarate as sole carbon source has been isolated from soil. Whole-cell preparations catalyze the oxidation of acetoacetate, acetate, glyoxylate, and citric acid cycle intermediates. Cell-free extracts of 3-hydroxy-3-methylglutarate-grown cells show an adenosine triphosphate, coenzyme A (CoA), and Mg(2+)-depend...
متن کاملSeparation of ( 3 . 14 C ) 3 - Hydroxy . 3 - methylglutaric acid from ( 3 _ 14 C ) 3 - Hydroxy - 3 - methylglutaryl CoA using Sephadex G - 15 column chromatography
A new method has been developed for the separation of (314C) 3-Hydroxy-3-methylglutaric acid from a (3_ 14C) 3-Hydroxy-3-methylglutaryl CoA preparation using Sephadex G-15 column chromatography. This method is simple, rapid and is useful in studies whe1'e the preparation of (3_ 14C) 3-Hyd1'oxy-3-methylglutaryl CoA is requi1'ed to bef1'eef1'Om (3_ 14C) 3-Hyd1'oxy-3-methylgluta1'ic acid contamina...
متن کاملSimultaneous liquid-chromatographic analysis for 4-hydroxy-3-methoxymandelic acid and 4-hydroxy-3-methoxyphenylacetic acid in urine.
We describe a rapid, reliable "high-performance" liquid-chromatographic method of simultaneously analyzing for 4-hydroxy-3-methoxymandelic acid (I) and 4-hydroxy-3-methoxyphenylacetic acid (II) in urine. Paired-ion chromatography and amperometric detection are used in the method. A 5-mL aliquot of urine is adjusted to pH 6.1 and subjected to anion-exchange chromatography (Dowex AG 1-X4, 1.8 X 0...
متن کاملDistribution of 3-hydroxy-3-met hylg
3-Hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase, E.C. 1.1.1.34), the major ratelimiting enzyme of the sterol biosynthetic pathway, was studied in ileal epithelial cells isolated in a villus-to-crypt gradient according to Weiser (Weiser, M. M. 1973.5. Bzol. Chem. 248: 2536-2541). Alkaline phosphatase (E.C. 3.1.3.1) served as a marker for the mature villus cells. Protease effec...
