Abstract
The enthalpy of combustion of DL-alpha -alanyl-DL-asparagine was measured in a liquid calorimeter with an isothermal jacket. The standard enthalpies of combustion (Delta H-c degrees = -3564.82 +/- 4.4 kJ/mol) and formation (Delta H-f degrees = -1042.25 +/- 4.4 kJ/mol) of the peptide were calculated. it was shown that the obtained value of Delta H-c degrees coincides with that calculated by the Hendrick additive-group methods within 1.5 and 1%, respectively.
