Ligand Efficiency Formula
The following formula is used to calculate the Ligand Efficiency.
EL = G / N
- Where EL is the Ligand Efficiency
- G is the Gibbs free energy (J)
- N is the number of non-hydrogen atoms
How to Calculate Ligand Efficiency?
The following two example problems outline how to calculate the Ligand Efficiency.
Example Problem #1:
- First, determine the Gibbs free energy (J). In this example, the Gibbs free energy (J) is given as 50.
- Next, determine the number of non-hydrogen atoms. For this problem, the number of non-hydrogen atoms is given as 144.
- Finally, calculate the Ligand Efficiency using the equation above:
EL = G / N
Inserting the values from above and solving the equation:
EL = 50 / 144 = .347
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
Gibbs free energy (J) = 100
number of non-hydrogen atoms = 5055
Entering these values yields:
EL = 100 / 5055 = .0197
