Abstract
Partial molar volumes, V o2 and partial molar heat capacities C op,2 have been determined in aqueous solution at 25°C for the dipeptides glycyl-L-asparagine, glycyl-DL-threonine, glycyl-DL-serine and glycyl-DL-phenylalanine. These results, along with those for some other dipeptides of sequence Gly-X, were used to estimate side chain contributions to V o2 and C op,2 . For these dipeptides both V o2 and C op,2 were found to be a linear function of the respective thermodynamic property for the amino acid X. The contributions of the glycyl units to V o2 and C op,2 of the dipeptide are discussed.
