Accurate absolute free energies for ligand–protein binding

WebAboutTranscript. Nuclear binding energy is the energy required to split an atom’s nucleus into protons and neutrons. Mass defect is the difference between the predicted mass and the actual mass of an atom's nucleus. The binding energy of a system can appear as extra mass, which accounts for this difference. Created by Jay. WebThe free energy of binding of a ligand to a protein ΔGbinding is split as:Gbinding=ΔGvacuo+ΔGsComplex−ΔGsLigand−ΔGsProteinwhere ΔGvacuo is the free energy of binding in vacuo, and ΔGsComplex, ΔGsLigand, ΔGsProtein are the solvation energies of the protein/ligand complex, the free ligand and the free protein, respectively. otmar graf weyherWebDec 28, 2024 · The binding energy per nucleon is the binding energy divided by the total number of neutrons and protons. This gives us information about the stability of a given nucleus. A high binding energy per nucleon would indicate a very stable nucleus – it is not likely to release energy if it decays into something else. otmar holz
