THERMODYNAMIC PROPERTIES OF PEPTIDE SOLUTIONS .12. ENTHALPIES OF DILUTION OF AQUEOUS-SOLUTIONS OF SOME GLYCYL DIPEPTIDES AT 298.15 K

Enthalpies of dilution at 298.15 K of aqueous solutions of the dipepti des glycyl-L-valine, glycyl-D-leucine, glycyl-L-asparagine, glycyl-L-t hreonine, glycyl-DL-threonine and glycyl-DL-serine have been determine d using flow microcalorimetry. The results obtained were used to deter mine the enthalpic interaction coefficients that characterise pair int eractions of the peptides in aqueous solution. These coefficients were compared with those for other dipeptides and also with those for some amino acids.
