Mathematically , ligand efficiency ( LE ) can be defined as the ratio of gibbs free energy ( Α G ) to the number of non-hydrogen atoms of the compound : Mathematically , ligand efficiency ( LE ) can be defined as the ratio of Gibbs free energy ( ΔG ) to the number of non-hydrogen atoms of the compound :
Secara matematik, kecekapan ligan (LE) boleh ditakrifkan sebagai nisbah tenaga bebas gibbs (G) kepada bilangan atom bukan hidrogen sebatian: Secara matematik, kecekapan ligan (LE) boleh ditakrifkan sebagai nisbah tenaga bebas Gibbs (G) kepada bilangan atom bukan hidrogen sebatian:
