6) Proteins are composed of amino acids polymerized into long chains. The structure of a protein - that is, its overall shape and how the chains are "folded” around each other - is very important for its function. In an aqueous environment, in an active, folded state the hydrophilic amino acids in the protein are facing outwards exposed to the water and the hydrophobic amino acids are hidden away from the water in the core of the protein. In a...

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...

I cannot seem to figure it out.
The standard Gibbs-free energy of a system is related to its equilibrium constant through the following equation. AG = R.T.In(K) In this equation R is the gas constant, T is the temperature, and the next to AG defines the conditions as standard ambient temperature and pressure, i.e. "SATP". (Answer the following questions to three significant figures.) (a) Given an equilibrium constant of 6.28 x 10-3, what is its standard Gibbs-free energy? 4.9 12.6...
