Partial molar heat capacities volumes and compressibilities of aqueous solutions of some peptides that model side-chains of proteins

Abstract

Partial molar volumes, heat capacities and compressibilities at infinite dilution are presented for some tripeptides of sequence glycyl-X-glycine, where X is an amino acid, in aqueous solution at 25°C. These results are used to estimate the amino acid side-chain contributions to the thermodynamic properties. The side-chain contributions are compared with those determined using thermodynamic data for other model compounds. © 1994, Walter de Gruyter. All rights reserved.
