Abstract
The enthalpies of dissolution of crystalline tyrosyl-proline in aqueous solutions of potassium hydroxide at 298.15K were determined by direct calorimetric method. Measurements were carried out on a calorimetric apparatus with automatic recording of the temperature-time curve. The values of standard enthalpies of combustion and formation of tyrosyl-proline were calculated by additive group method based on group systematics with Benson classification-type fragment classification, which takes into account the influence of the initial environment for atoms. The standard enthalpies of formation of the dipeptide and its dissociation products in aqueous solution were calculated.
