Citric Acid Determination
Three types of methods have been proposed for the determination of citric acid in urine. Salant and Wise (1) used the unspecific mercuric sulfate reagent of Deniges (2) in a study of the toxicity of citrates. Thunberg (3) developed an enzymatic method employing a dehydrogenase said to be specific for citrate. The remaining methods depend on the so called pentabromoacetone method of Stahre (4), ...
متن کاملA microcolorimetric method for the determination of citric acid.
In 1947 we (1) described a microcolorimetric method, with a range of sensitivity from 10 to 60 y, for the determination of citric acid in small samples of blood and urine. This method was based on the conversion of citric acid to pentabromoacetone and on the subsequent reaction between pentabromoacetone and alcoholic sodium iodide with the development of a yellow color complex. Hydrazine sulfat...
متن کاملA rapid method for the determination of citric acid.
Numerous methods, enzymatic and chemical, have been reported for the determination of small amounts of citric acid in biological fluids. Of the chemical methods the majority involve the conversion of the citric acid to pentabromoacetone, which may be estimated by various gravimetric, titrimetric, or calorimetric procedures. The more recent modifications (l-3) of the met.hod have simplified it a...
متن کاملD-Isocitric acid
Mix**, wait for the end of the reaction (approx. 10 min) and read the absorbances of the solutions (A2). If the reaction has not stopped after 10 min, continue to read the absorbances at 2 min intervals until the absorbance increases constantly over 2 min. Determine the absorbance differences (A2-A1) for both, blank and sample. Subtract the absorbance difference of the blank from the absorbance...
متن کاملeffect of food additive citric acid on the growth of human esophageal carcinoma cell line ec109
objective: today, esophageal cancer (ec) has become one of the most common cancer types in china. therefore, new drug and therapeutic strategies are urgently needed to improve postoperative survival rate of patients with ec. as a food additive, several lines of evidence have shown that citric acid can be served as glycolysis suppressor to inhibit growth of some tumor cells. however, little is k...
