摘要：

Partial molar heat capacities of the three tripeptides glycylglycylglycine, glycyl-L-alanylglycine and glycyl-DL-threonylglycine in aqueous solution at the temperatures 50, 75, 100 and 125 degrees C have been determined using differential flow calorimetry. The results have been used to estimate the contributions to the partial molar heat capacities of peptides of the alanyl and threonyl side-chains. These side-chain contributions are compared with those reported in the literature.
