Chemistry

The formation of a dipeptide is the first step toward thesynthesis of a

protein molecule. Consider the following reaction:

glycine (aq) + glycine (aq) à glycylglycine (aq) + H2O (l)

Given that the standard formation free energies forglycylglycine (aq), glycine (aq) and

water are respectively – 487.9 kJ/mol, – 315.9 kJ/mol and –237.13 kJ/mol, calculate

DRGo’ and the equilibrium constant at 298 K, keeping in mindthat the reaction is carried

out in an aqueous buffer solution. Assume that the value isessentially the same at 310K.

What conclusion can you draw from your result?
