Estimation of Alpha-amino Nitrogen in Plasma and Urine by the Colorimetric Ninhydrin Reaction.
نویسندگان
چکیده
Methods are described for the estimation of plasma and urine alpha-amino nitrogen by the colorimetric ninhydrin reaction; in the method for urine, both ammonia and urea are separated by a rapid ion-exchange resin procedure. Two methods of estimation are given; one has the advantage of great simplicity, but involves the use of cyanide; in the other, cyanide is eliminated. Normal values are reported; they correspond well with those obtained by the gasometric ninhydrin method.

The colorimetric estimation of alpha-amino nitrogen in tissue fluids.
Various authors have reported methods for the colorimetric estimation of alpha-amino nitrogen with ninhydrin (Moore and Stein, 1948, 1954; Smith and Agiza, 1951 ; Troll and Cannan, 1953; Yemm and Cocking, 1955; Kalant, 1956; Rosen, 1957). Only Kalant has applied this method to the direct measurement of alpha-amino nitrogen in biological fluids; he reported on the determination of total alpha-am...
متن کاملDetermination of the Plasma Glycine after Gelatin Feeding as a Diagnostic Procedure for Pancreatic Fibrosis.
A retardation of the absorption of amino acids derived from ingested protein into the bloodstream is known to result from a failure of the secretion of the pancreatic proteinases. West, Wilson and Eyles (1) have shown that a much smaller rise in blood amino nitrogen occurs in children with pancreatic fibrosis than in normal children after a test meal of casein. Preliminary results obtained by t...
متن کاملA photometric method for the determination of proline.
The characteristic red color produced when proline interacts with ninhydrin in acidic solutions has recently been proposed for use in the quantitative assay of this imino acid (1,Z). These methods could not, however, be applied directly to the estimation of proline in biological fluids, since other amino acids interfere to some extent and must be removed either by chromatography (1) or by destr...

The 'glycine tolerance test', an oral dose of glycine followed by analysis of peripheral blood samples, was first used for investigating amino acid absorption more than 30 years ago by Heath and Fullerton (1935), who, though they did not investigate any cases of unequivocal malabsorption, concluded that the test gave 'no useful information regarding the rate of absorption from the gastrointesti...

A simple procedure for the estimation of plasmaamino nitrogen basedon the reaction of amino groupswith 2,4-dinitrofluorobenzene (DNFB) and subsequentmeasurement of the dinitrophenyl (DNP) amino derivatives at 420 m is presented. Elevated concentrations of bilirubin, hemoglobin, and the major nonprotein and nonamino acid nitrogen components of plasma do not seriously interfere. The proposed proc...
