Een ligand in de biochemische betekenis van het woord is een molecuul dat aan een ander, doorgaans groter molecuul kan binden, zoals een signaalmolecuul aan een membraaneiwit. Een ligand kan alleen een binding aangaan met een specifiek doelmolecuul (een nucleïnezuur of eiwit ). Ligand binding can affect the function of proteins and often causes conformational change in the protein target. Since form fits function, determining the secondary structure of proteins with and without ligands is essential for a more complete understanding of how the ligand alters the protein’s structure and function.
In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I discuss receptors and ligands. I explain the differen consequence of ligand binding is that the protein is stabilized against unfolding and is less flexible . . . [This is] a consequence of the ligand binding more tightly to the fully folded conformation (N) than to the fully unfolded state (U) and any distorted or par- tially unfolded forms that result from flexibility of the structure.” The ligand is said to be "pre-organized" for binding, and there is little entropy penalty for wrapping it around the metal ion. For example heme b is a tetradentate cyclic ligand which is strongly complexes transition metal ions, including (in biological systems) Fe +2 .
Receptor/ligand binding affinity. The interaction of ligands with their binding sites can be characterized in terms of a binding affinity. In general, high-affinity ligand binding results from greater attractive forces between the ligand and its receptor while low-affinity ligand binding involves less attractive force.

Reliable measurement of ligand binding to cell surface receptors is of outstanding biological and pharmacological importance. Resonance energy transfer–based assays are powerful approaches to achieve this goal, but the currently available methods are hindered by the necessity of receptor tagging, which can potentially alter ligand binding properties.

Ligand (L) binding to a molecular target (P) can be represented as a thermodynamic and kinetic process in which the binding constant K b measures the thermodynamic stability of the binding complex (free‐energy), while the binding and unbinding rate constants k on and k off, respectively, define the kinetics with the k off determining the residence time of the ligand in the target structure. 2013-01-22
It binds at the same binding site, and leads, in the absence of the natural ligand, to either a full or partial response. In the latter case, it is called a partial agonist.

Ligander (från latinets ligandum, bindning) kallas de (ofta mindre molekyler) som har specificitet för en receptor och genom att komplexbinda till receptorn, fortplantar någon form av signal inne i cellen.
Intracellular receptors, ligand-gated ion channels, G protein-coupled receptors, and receptor tyrosine kinases. Ligand-gated ion channels (LICs, LGIC), also commonly referred to as ionotropic receptors, are a group of transmembrane ion-channel proteins which open to allow ions such as Na +, K +, Ca 2+, and/or Cl − to pass through the membrane in response to the binding of a chemical messenger (i.e.
Ligand Binding Our ligand binding group offers support for Immunogenicity, PD, PK, BE, and Biosimilar studies for both preclinical and clinical stages of drug development. We have nearly a decade of experience with small and large molecules, such as oligonucleotides, small peptides, chemical elements, proteins, bi-specific antibodies, monoclonal antibodies, and antibody-drug conjugates. In principle, a ligand binding assay should be able to detect the binding of any orthosteric ligands regardless of their functional effects.
