These pints are divided into two cups (though the imperial cup is rarely used now), which in turn are divided into two gills (gills are also rarely used). Thus a gallon is equal to four quarts, eight pints, sixteen cups or thirty-two gills.
Binding constant. Home Â» Binding constant. Definition. noun. A mathematical constant that describes the bonding affinity between two molecules at equilibrium. Supplement. It is the measure of the affinity of an enzyme for its substrate. An example is the measure of the strength of binding in the hapten-antibody interaction.
In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. In protein-ligand binding, the ligand is usually a signal-triggering molecule binding to a site on a target protein.The binding typically results in a change of conformation of the target protein. In DNA-ligand binding studies, the ligand can be a small molecule, ion, or protein that binds to the DNA double helix.The binding occurs by intermolecular forces, such as ionic bonds, hydrogen bonds and van der Waals forces. The docking (association) is usually reversible (dissociation).n DNA-ligand binding studies, the ligand can be a small molecule, ion, or protein that binds to the DNA double helix. The binding occurs by intermolecular forces, such as ionic bonds, hydrogen bonds and van der Waals forces.
