Compartmentation of Free Amino Acids

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...

Variations in sucrose,total free amino acids and nitrates of sugarbeets during the growing season under high nitrogen untritional conditions

Pattern of activity levels of amino trnasferases in the gonads of silkworm, Bombyx mori L.on exposure to prostaglandin F2

The impact of PGF2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, Bombyx mori L. were investigated in the present experiment. The effect of PGF2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. The enhanced activity levels of amin...

Theoretical Thermodynamic Study of Arginine and Lysine Amino Acids at different Solvents

The thermodynamic functions such as enthalpy, H°, Gibbs free energy, G°, and entropy, S°, of Arginine and Lysine amino acids were theoretically studied at different polar solvents by using ²Gaussian o3², software. First, the structural optimization of isolated Arginine and Lysine were done in the gas phase by applying the Density Functional Theory (B3LYP) level ...

Effects of long-term frozen storage on the compositions of free amino acids and nucleotide-related compounds of the coconut crab Birgus latro

This study examined the effects of long-term frozen storage (-20 °C for 5 months) of free amino acids (FAAs) and nucleotide-related compounds (NRCs) in muscle and hepatopancreas of the coconut crab Birgus latro. Although long-term frozen storage had little effect on FAA composition in muscle, the amounts of several FAAs increased in the hepatopancreas that may be the result of protein decomposi...

Blood Amino Acid Compartmentation in Mice Bearing Lewis Lung Carcinoma1

Blood amino acid compartmentation between plasma and red blood cells was studied in mice bearing the Lewis lung carcinoma. The animals showed a change in compartmentation with an increase in the concentra tion of most amino acids in the plasmatic fraction with the exception of glycine, glutamine, aspartate, asparagine, and taurine. This work focuses on the importance of studying the distributio...
