using partial molar volume data, V t , in aqueous solution at 25Β°C for some peptides of sequence Gly-X-Gly, where X is an amino acid. These side-chain partial molar volumes are critically compared with those obtained using V data for amino acids. It is concluded that side-chain partial molar volumes

The partial molar volumes of glycine, DL-alanine, DL-serine, DL-threonine, L-histidine and glycylglycine were obtained in water and aqueous solutions of 0.15 mol β’ dm -3 dimethyl sulfoxide, 2.0 mol β’ dm -3 sodium chloride and 0.15 mol β’ dm -3 dimethyl sulfoxide/2.0 mol β’ dm -3 sodium chloride at T =
The partial molar isentropic pressure coefficients at infinite dilution k a S, 2 =-(1V a 2 /1p)S , where V a 2 is the partial molar volume at infinite dilution, have been determined for six N-acetyl amino acid and peptide amides in aqueous solution at the temperature 298.15 K. The results obtained h
Relative densities and massic heat capacities have been determined for the amino acids L-lysine monohydrochloride and L-arginine monohydrochloride in aqueous solution at the temperatures T = (288. 15, 298.15, 313.15, and 328.15) K. These data have been used to calculate apparent molar properties whi
