Molecular docking

Definition

Molecular docking is a computational technique used to predict the preferred orientation of one molecule, typically a drug or ligand, when it binds to a target protein. This process helps researchers understand the interactions between molecules, which is crucial for drug design and development. By simulating how different compounds fit into specific binding sites of proteins, molecular docking aids in identifying potential new drugs and optimizing existing ones.
