Umbrella Sampling Simulation Service
Umbrella sampling simulation is a molecular dynamics simulation method for calculating the free energy difference of a molecule under a complex potential energy surface. The method guides a molecule from one state to another by applying an applied potential field, and the free energy difference between the two states is obtained by calculating the potential energy difference corresponding to the applied potential field. This technique is particularly important in the study of protein-ligand binding, protein-protein interactions, and membrane permeation processes. This technique yields indispensable data concerning the potential energy of proteins, the behavior of biomolecules, and pathways of biological reactions. As a global leaders in the field of computer-aided drug design, CD ComputaBio provides expert umbrella sampling simulation services.
