Ligand: Definition, Examples, and How It Works - Biology Dictionary
2018年4月22日 · 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.
Ligand - Wikipedia
In coordination chemistry, a ligand[a] is an ion or molecule with a functional group that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electron pairs, often through Lewis bases. [1] .
Ligand (biochemistry) - Wikipedia
In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. The etymology stems from Latin 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.
Ligands: Definition, Types, and Examples - Chemistry Learner
A ligand is a molecule or ion that can donate a pair of electrons to a central metal atom or ion. The donated electron pair forms coordinate bonds with the metal, forming coordination compounds. Ligands act as Lewis bases (electron pair donors), and the central atom acts as a Lewis acid (electron pair acceptor).
Ligands - Definition, Types & Examples - BYJU'S
A ligand is an ion or molecule which donates a pair of electrons to the central metal atom or ion to form a coordination complex. The word ligand is from Latin, which means “tie or bind”. Ligands can be anions, cations, and neutral molecules.
Ligands: Definition, Types, Examples, Denticity and Coordination
2024年1月30日 · Ligands are ions or molecules that form a bond with the central atom of a coordination compound by donating its pair of electrons to it. A ligand may be positively charged, negatively charged, or neutral.
Ligand | Bonding, Coordination, Receptors | Britannica
coordination compound, any of a class of substances with chemical structures in which a central metal atom is surrounded by nonmetal atoms or groups of atoms, called ligands, joined to it by chemical bonds.
What is ligand in biology? - California Learning Resource Network
2025年1月4日 · In biology, a ligand is a molecule that binds to a specific site on a target protein, such as an enzyme, receptor, or ion channel, to modulate its activity or function. Ligands can be small molecules, peptides, proteins, or even entire cells, and they play a crucial role in many biological processes, including signal transduction, cell ...
Ligand Definition in Chemistry - ThoughtCo
2019年11月6日 · A ligand is an atom, ion, or molecule that donates or shares one or more of its electrons through a covalent bond with a central atom or ion. It is a complexing group in coordination chemistry that stabilizes the central atom and determines its reactivity.
Definition of ligand - Chemistry Dictionary
What is a Ligand? A ligand is an ion or molecule that binds to a central metal atom to form a complex (alternatively known as a coordination entity). Ligands are usually thought of as electron donors attracted to the metal at the center of the complex. Metals are electron acceptors.
