The amino acids were: arginine (basic), tryptophan (neutral and hydrophobic),valine(neutral and hydrophobic) and aspartic acid (acidic). From theCambridge English Corpus The residue changes are glycine at position 82 (previously glutamic acid), threonine at position 218 (previously asparagine) andva...
An above-mentioned problems, valine, isoleucine, solid solutions and this aliphatic neutral amino acids consisting of three amino acids leucine, oxy neutral amino acid amide neutral amino, acidic amino acids, basic amino acids, hydroxy acids is solved by at least one added solid solution selected ...
Addition of acidic, basic or some neutral amino acids that are known to be poor inhibitors of valine uptake did not cause significant quantities of label to appear in the medium. For the unfertilized eggs, the concentration of acid-soluble label remained many hundreds of times greater in the ...

The rates of exchange are strongly dependent on the temperature, solvent, concentration, and presence of acidic and basic impurities. In CDCl3, the presence of acidic impurities (usually from solvent decomposition) leads to rapid acid-catalyzed exchange between H-bonded groups. In solvents like DMSO...
Competition experiments with other amino acids show that the Na + -dependent carrier is highly specific for neutral amino acids, as indicated by the high inhibition constants of basic and acidic amino acids. Our results suggest that the energy supplied by zooxanthellae photosynthates is necessary ...
In contrast, basic KVCit probe 1e showed the shortest half-life of all probes (t1/2 = 0.9 h). These results indicate that an acidic side chain at the P3 position can effectively repel access of Ces1c, inhibiting the cleavage reaction. Probes 1a–e tested were stable in human ...
The electrode of the cell was calibrated with 0.05 mol L-1 potassium hydrogen phthalate solution in the acidic region and with 0.01 mol L-1 borax solution in the alkaline region. The effect of variation in asymmetry potential, ...
Improving animals' immune function. L-Valine can motivate animal bones T cells to transform into mature T cells. The shortage of valine decreases addiment C3 and transferritin levels, significantly impeding growth of thymus and peripheral lymphoid tissue and causing growth inh...
Thus, it is necessary to remove the BOC group, which is always removed under acidic conditions33. The trifluoroacetic acid method has primarily been adopted for this experiment. However, when alkali is used to neutralize the trifluoroacetic acid after removal of the BOC protecting group, the ...
