RESUMO
The partial molar heat capacities have been determined for the series of peptides alanyl(glycyl)(x)glycine, x=1-3, and for the compounds N-acetylglycinamide and N-acetyl glycylglycinamide in aqueous solution over the temperature range 10-100 degrees C using high sensitivity scanning microcalorimetry. The partial molar volumes for these compounds have also been determined over the temperature range from 10 to 90 degrees C using a scanning densimetric method. The results were used to derive the partial molar heat capacities and volumes of the glycyl group at temperatures in the range 10-100 degrees C. The results obtained are critically compared with literature results derived using heat capacity and volume data for some oligoglycines.
