Determination of L- Ascorbic Acid in Plasma by Voltammetric Method
Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). L-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...

متن کاملDEVELOPMENT OF A METHOD FOR THE DETERMINATION OF 4-HYDROXY-3-METHOXYMANDELIC ACID (VANILLYLMANDELIC ACID) IN URINE BY PAPER CHROMATOGRAPHY
We have developed a simple and precise paper chromatographic method for the determination of 4-hydroxy-3-methoxymandelic acid (VMA) in urine. Concentrations of VMA in patients with neuroblastoma were increased in comparison to controls. The linearity was excellent in the concentration range tested. The within-assay coefficient of variation for control and patient urine was less than 2.2%. ...
متن کاملA Method for the Determination of Adenosine- 5’-phosphoric Acid and Its Homologues*
For the determination of adenosine-5’-phosphoric acid and its homologues the methods which have been recommended chiefly are (1) enzymatic deamination by deaminase and quantitative determination of the ammonia split off (1) ; (2) determination on the basis of the pharmacological activity, (a) contraction of the isolated guinea pig uterus, (b) the characteristic change in the electrocardiogram u...
متن کاملCcxxv. Studies on Bacterial Phosphatases. I. the Decomposition of Phosphoric Acid Esters by Clostridium Acetobutylicum
THE conception of the phosphoric esterification of sugars as a necessary step in their metabolism in bacterial cells follows logically from considerations of carbohydrate breakdown in muscle and in yeast. But the experimental evidence in support of this conception in the case of bacteria is not very extensive, and information regarding the bacterial phosphatase systems which are responsible for...
