Web22 apr. 2024 · In biochemistry, a ligand is any molecule or atom which binds reversibly to a protein. A ligand can be an individual atom or ion. It can also be a larger and more complex molecule made from many atoms. A ligand can be natural, as an organic or inorganic molecule. A ligand can also be made synthetically, in the laboratory. WebIn biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. The etymology stems from ligare, which means 'to bind'.In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein.The binding typically results in a change of …
