The method of The, Fleury And Vink for the determination of phenylpyruvic acid (PPA) in urine is modified by measuring the extinction after the green colour with ferric chloride has faded, and subtracting this extinction from that found initially. More accurate values are obtained and low PPA ...
phenylpyruvic acidphosphateurineTo 4 ml. urine is added 1 ml. of solution containing 11 g. MgCl2, 14 g. NH4Cl and 22.5 ml. 25 per cent. NH3 per litre. Two drops 10 per cent. HC1 and 1 to 3 drops 10 per cent. FeCl3 are added to the filtrate obtained after standing for 5 min....
4.1 Urine organic acid profile Phenylpyruvate, phenyllactate, and phenylacetate show increased urine excretion in PKU patients. Mandelate is often also increased. Although PKU is normally diagnosed by measuring plasma phenylalanine concentrations, it can also be detected by the presence of these metaboli...
The keto-acid was not obtained in the solid state. The colorimetric method for testing PPA traces in urine depends on the formation of a enol-Fe3+ complex (2:1) which appears stable in dimethylsulfoxide (DMSO). : Phenylpyruvic Acid; Tautomerism Received: 1975-6-1 Revised: 1975-10...
well-known for its use as herbal tea, is increasingly studied for its metabolic benefits. Prospective studies linking diet rich in polyphenols from rooibos to reduced diabetes associated cardiovascular complications have not been extensively assessed. Aspalathin, a flavonoid, and phenylpyruvic acid-2-...
There is provided an antidiabetic enolic glucoside of phenylpyruvic acid and derivatives thereof for use as medicaments, especially normoglycemic agents, i.e. for lowering blood glucose levels to normal levels in mammals that are obese, pre-diabetic or have diabetes, obesity and/or syndrome X. ...
25 per cent. NH3 per litre. Two drops 10 per cent. HC1 and 1 to 3 drops 10 per cent. FeCl3 are added to the filtrate obtained after standing for 5 min. The green colour which is sometimes masked by the presence of phosphate in urine is then obtained. A. Hepburn.关键词:...
In all these cases the temperature coefficient of kill by contact action was greater for colloid than for crystals. Dieldrin and 2-bromomercurithiophen had positive temperature coefficients of kill by contact action. With dieldrin, the...
Conclusion: As a result, a fast, inexpensive LC-MS/MS method has been developed for 3-Phenylpyruvic acid.Canbay, ErhanCanbay, Zeynep elikYeilyurt, BerrakDoan, SerinArabaci, remSezer, Ebru DemirelSzmen, EserEge Journal of Medicine
Phenylacetic acid, phenylalanine, tyrosine and methionine were also present in excess in the urine. Some possible modes of formation of the α-hydroxy-butyric acid are discussed.doi:10.1136/adc.33.168.109Alan J. SmithLeonard B. StrangArch Dis ChildArchives of Disease in Childhood...
