 <abstract xml:lang="en">
 <p>The kinetics of the reactions of Gly, L-Pro, and DL-Val with 4-nitrophenyl acetate in the water (0.671–0.911 mol.%)–1,4-dioxane system was studied. It was found that the reaction rate constants increase nonlinearly with increasing water content in the solvent. Quantum-chemical modeling of solvate complexes of the anionic form of glycine with binary solvent components was performed. It was found that the energies of their HOMO can be used as descriptors of the electronic structure of solvates. It is shown that the nonlinear dependences of the amino acid acylation rate constants on the binary solvent composition are due to the peculiarities of the specific solvation of α-amino acids.</p>

 <p>Исследована кинетика реакций Gly, L-Pro, DL-Val с 4-нитрофенилацетатом в системе вода (0,671–0,911 мол. %) – 1,4-диоксан. Установлено, что константы скорости реакций нелинейно возрастают с увеличением содержания воды в растворителе. Проведено квантово-химическое моделирование сольватных комплексов анионной формы глицина с компонентами бинарного растворителя. Установлено, что в качестве дескрипторов электронной структуры сольватов могут использоваться величины энергий их ВЗМО. Показано, что нелинейные зависимости констант скорости ацилирования a‑аминокислот от состава бинарного растворителя обусловлены особенностями специфической сольватации a-аминокислот.</p>
