In a differential scanning calorimetry experiment, the melting temperature, Tm, of a certain protein is found to be 46 C and the enthalpy of denaturation is 382 kJ/mol.
a. Estimate the entropy of denaturation assuming that the denaturation is a two-state process; that is: native protein<=>denatured protein.
b. The single polypeptide protein chain has 122 amino acids. Calculate the entropy of denaturation per amino acid. Comment on your results.
