✦ Synopsis

The regression correlative analysis of the aqueous-organic solvents' (water-methanol, water-ethanol and water-propan-2-ol) effect on the strength of amino acids (α-alanine, valine) has been provided at 298.15 K. Energetic contributions of acceptor ΔΔG d,1

0 (E T N ) and cohesion ΔΔG d,1 0 (δ N 2 ) properties of water-organic solvents into amino acid strength with carboxylic groups change ΔΔG d,1 0 , and energetic contributions of acceptor ΔΔG d,2

0 (E T N ), cohesion ΔΔG d,2 0 (δ N 2 ) and dielectric ΔΔG d,2 0 (ε N -1 ) properties of water-organic solvents into amino acid strength with amino groups change ΔΔG d,2 0 are evaluated.
