WebOct 18, 2024 · In the end, the governing forces of protein folding are the laws of thermodynamics. One important equation within chemistry and biochemistry is the Gibbs free energy equation: ΔG = ΔH – TΔS. Where G is Gibbs free energy, H is enthalpy, and T and S are temperature (held constant in the reproduced equation) and entropy, … WebBut you should, of course, know how to calculate this from enthalpy changes of formation. ΔH° = -890.4 kJ mol -1. So if you had to calculate the Gibbs free energy change at, say, 298 K, you can just slot the numbers in: ΔG° = ΔH° - TΔS°. ΔG° = -890.4 - 298 (-0.2442) = -817.6 kJ mol -1. It is easy as long as you remember to convert the ...
