Question 4 Many biological macromolecules undergo a transition called denaturation. Denaturation is a process whereby a structured, biologically active molecule, called the native form, unfolds or becomes unstructured and biologically inactive. The equilibrium is Native (folded) # denatured (unfolded) For a protein at pH = 2 the enthalpy change associated with denaturation is AH° = 418.0 kJ/mol and the entropy change is AS° = 1.3 kJ/K.mol both at 298.15K (a) Calculate the Gibbs free energy of denaturation of the protein...

5. In an equilibrium denaturation experiment, one makes up a series of different protein solutions, 1, 2, ..., M, having different amounts of urea, a denaturing agent, x1, x2, ..., XM. Then, for each particular solution, having denaturing agent in amount x, one measures the proportion f(x) of native protein molecules and the proportion fo(x) = 1 - fr of denatured protein molecules. Increasing the denaturing agent increases the population of Drelative to N. In the absence of denaturing agent,...

Question 5 Part A Biological macromolecules such as proteins may be positively, negatively, or neutrally charged depending on what amino acids are present. Some parts of a macromolecule may be positively charged while others are negatively charged, and this can affect the conformation - the shape of the macromolecule. Changes in the conformation may affect the function of a macromolecule. Two charged macromolecules (labelled 1 and 2) have charges q1 =+3.20 * 10-19 C and q2 =+12.8 10-19 C. They...
