Volumetric and Solvation Properties of Glycyl-Glycine and Glycyl-l-leucine in Aqueous Acetate Solutions

摘要: The densities of glycyl-glycine (diglycine) and glycyl-l-leucine, in water aqueous sodium acetate, potassium magnesium acetate calcium solutions, were measured at 298.15 K. apparent molar volumes, V 1, the partial $$ \bar{V}_{1} $$ , diglycine glycyl-l-leucine have been calculated. solvation number, n S, was also limiting volumes studied peptides analyzed terms Setschenow relationship. effect salt solutions on volumetric properties discussed coefficients, k 1. results indicate that volume is higher than values increase with concentration co-solutes (NaA, KA, MgA CaA). peptide interactions are stronger MgA/CaA NaA/KA. Also data suggest NaA KA CaA. Further, from to glycyl-l-leucine. It noted numbers for less decrease as increases.
