摘要：
The partial molar volumes, V-2(o), and partial molar heat capacities, C-p(o).(2), at infinite dilution have been determined for the compounds N-acetylasparaginamide, N-acetylglutaminamide, N-acetyltyrosinamide, and N-acetyllysinamide monohydrochloride in aqueous solution at T = (288.15, 298.15, 313.15, and 328.15) K. These results, along with the literature data for the compound N-acetylglycinamide, have been used to calculate the amino acid side-chain contributions to the thermodynamic properties. These side-chain contributions are compared with those obtained using small peptides as side-chain model compounds. (c) 2006 Elsevier Ltd. All rights reserved.
