چکیده

In man, the relative concentrations of a-amino nitrogen in tungstic acid filtrates of erythrocytes and plasma have been determined by Hamilton and Van Slyke, using the ninhydrin method (2). Dunn et al. (3) reported assays of free tryptophan in blood serum, plasma, and red blood cells by microbiological means with Lactobacillus arabinosus. More recently, Gutman and Alexander (4) determined the level of free glycine and alanine in plasma and red cells by chemical methods under fasting and non-fasting conditions. The plasma levels of ten individual amino acids in thirtythree normal men and women have been previously reported from this laboratory (5). There is being reported here the concentrations of twelve amino acids determined simultaneously in the red blood cells and in the plasma of twenty-four normal men.

Theoretical study of the solvent effects on the thermodynamic functions of Alanine and Valine Amino Acids

Using Gaussian 03, software the thermodynamic functions such as Gibbs free energy, G, Enthalpy, H, and Entropy, S, of Alanine and Valine amino acids were theoretically studied at different solvents. First, the Density Functional Theory (B3LYP) level with 3-21G, 6-31G and 6-31+G basis sets were employed to optimization of isolated Alanine and Valine amino acids in the gas phase. Moreover, Vib...
