摘要：

The dissolution enthalpies (Delta H-sol(m)) of DL-alpha-alanyl-DL-alpha-valine (AlaVal) and DL-alpha-alanyl-DL-alpha-norleucine (AlaNln) in aqueous solutions of dodecyl sulfate (SDS) at SDS concentration of m(SDS) = 0.05 mol.kg(-1) and peptide concentration m = 0.010 to 0.025 mol.kg(-1) at T = 298.15 K were measured via calorimetry. The results obtained have been used to calculate the transfer enthalpies (Delta H-tr(m)) of AlaVal and AlaNln from water into (water + SDS) micellar solution. Thermochemical characteristics of the transfer of AlaVal, and AlaNln in the investigated range of peptide concentrations are compared. The results are interpreted by considering ion-ion, ion-polar, and hydrophobic-hydrophobic interactions between the dipeptides and SDS micelles.
