In the context of drug discovery and chemical biology, ligands are small (usually organic) molecules that are recognized by and bind specifically and stoichiometrically to proteins.

For enzymes, "ligand" often means inhibitors, but also includes substrates.

For receptors, "ligand" can mean either agonists, antagonists or reverse agonists.
