affinity

An expression of the strength of interaction between two entities, eg. between receptor and ligand or between enzyme and substrate. The affinity is usually characterized by the equilibrium constant association constant or dissociation constant for the binding, this being the concentration at which half the receptors are occupied.

Affinity

[taxonomy] Affinity (taxonomy) – mainly in life sciences or natural history – refers to resemblance suggesting a common descent, phylogenetic relationship, or type. The term does, however, have broader application, such as in geology (for example, in descriptive and theoretical works), and similarly in astronomy (for example, see `Centa...

Affinity

Affinity is the tendency of a molecule to associate with another. The affinity of a drug is its ability to bind to its biological target (receptor, enzyme, transport system, etc.) For pharmacological receptors it can be thought of as the frequency with which the drug, when brought into the proximity of a receptor by diffusion, will reside at a pos...
