Amino acid concentrations were determined in whole blood, plasma and washed erythrocytes from a group of healthy subjects. A comparison between the erythrocyte concentrations calculated from whole blood and plasma concentrations and those measured in washed erythrocytes showed that several amino acids (especially methionine, valine, isoleucine, leucine, tyrosine and phenylalanine) can easily be washed out of the erythrocytes. Statistical analysis of the data indicates that at least three… Expand
Simultaneous measurements of free amino acid patterns of plasma, muscle and erythrocytes in healthy human subjects.
There were significant positive correlations between plasma, muscle and RBC AA concentrations for a large number of AA, specially BCAA, and the RBC BCAA concentrations correlated most strongly with the ratio of alkali-soluble protein to DNA in skeletal muscle and were also significantly correlated to serum albumin and total proteins.

Erythrocytes participate significantly in blood transport of amino acids during the post absorptive state in normal humans
The hypothesis that both blood compartments, plasma and erythrocytes, are involved significantly in the blood transport of amino acids in humans during the postabsorptive state is supported. Expand
The effects of changes in plasma amino acid concentrations on erythrocyte amino acid content.
In order to determine the effects of large variations in plasma amino acid concentrations upon human erythrocyte amino acid content, the plasma concentration of blood samples was enhanced (x 3.8) byExpand
Blood cell to plasma gradients of amino acids in arterial and venous blood in fed and fasted rats.
In general, the role of erythrocytes in amino acid transport was enhanced in starvation, and blood cells became the main determinants of C/P changes, mainly in starvation. Expand

1) A simple, rapid analytical method for amino acids and polyamines in erythrocytes within a blood volume of 1 ml with a quantitative limit of precision ranging from 1-10 p moles was establishedExpand
Role of the plasma and erythrocytes in veno-arterial portal changes during post prandial state in the rat.
The data suggest that in vivo during the time of contact between blood and organ tissues, some amino acids but not all are significantly taken up by the erythrocytes, particularly tyrosine and essential amino acids. Expand
A significant pool of amino acids is adsorbed on blood cell membranes
Results showed that a pool of amino acids representing 21.1% of the whole blood cell amino acids was adsorbed on the blood cell membranes of adult Wistar rats, where non-polar amino acids showed high adsorption on the membrane, whereas out of the polar amino acid group, only the non-ionic amino acids did adsorb.

Postprandial distribution of free amino acids between plasma and erythrocytes of common carp (Cyprinus Carpio L.)
Levels of essential free amino acids in whole blood and plasma were positively correlated with their levels in the diet and among these amino acids which have shown the concentration ratio (erythrocyte-plasma) below unity were leucine, valine, histidine and lysine. Expand
In vitro adsorption of amino acids onto isolated rat erythrocyte membranes.
This study shows that alanine, glycine, glutamine, phenylalanine and leucine, but not glutamate, adsorbed onto erythrocyte membranes according to Michaelis-Menten-like kinetics as an effect of 24-hr starvation. Expand
Influence of branched-chain amino acid infusion on arterial concentrations and brain exchange of amino acids in patients with hepatic cirrhosis
Patients with hepatic cirrhosis show a decreased whole blood concentration of aspartate indicating a reduced intracellular concentration of this amino acid, and the brain uptake of tyrosine and fractional uptake of leucine and valine is augmented in patients with hepatitis, demonstrating abnormal brain amino acid uptake in this disorder.

Blood Cell and Plasma Amino Acid Levels Across Forearm Muscle During a Protein Meal
It appears that both blood cells and plasma transport amino acids from the splanchnic bed to the periphery and that both participate actively in the deposition of amino acids in the forearm of the subject studied. Expand
Cationic amino acid transport in the rabbit reticulocyte. Na+-dependent inhibition of Na+-independent transport.
The result is that, on the addition of one of these two amino acids in excess, Na+ is changed from a stimulant to an inhibitor of diamino acid transport. Expand
Biochemical Studies of Erythrocytes in a Patient with Pyroglutamic Acidemia (5-Oxoprolinemia)
The patient's overproduction of pyroglutamate is probably caused by increased in vivo activity of γ-glutamyl-cysteine synthetase due to absence of normal feedback inhibition by glutathione, with a resulting abundance of substrates available for γ -glut amyl cyclotransferase. Expand
Effect of insulin on muscle glutamate uptake. Whole blood versus plasma glutamate analysis.
The need for both whole blood and plasma amino acid analysis in investigations concerned with protein synthesis and/or amino acid flux, for analysis of plasma samples alone could be misleading as illustrated in the present study. Expand
Muscle nitrogen metabolism in chronic hepatic insufficiency.
It is suggested that muscle plays an important role in disposing ofNH3 in patients with hepatic insufficiency and a major fraction of NH3 taken up by muscle is released as glutamine. Expand
Differences in schedules of regression of transport systems during reticulocyte maturation.
The complexity of the transport characteristics for amino acids of a reticulocyte-rich population of young blood cells and the mature erythrocyte may mean that two glycine transport systems are present, but support for this view was not obtained by the test of analogues for differential inhibition of the two components or by the finding of any difference in the rate of regression during reticULocyte maturation.

Abstract This paper describes seemingly trivial variations in the preparation of blood plasma for amino acid analysis, and in the operation of the automatic amino acid analyzer, that can lead toExpand
A rapid column chromatographic procedure for the routine measurement of taurine in plasma of normals and depressed patients.
A rapid method has been developed for the routine measurement of taurine in plasma using the excellent sensitivity and specificity of the analytical column of the automatic amino acid analyzer to assay multiple samples in a relatively short period of time. Expand
