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.
Monodentate ligands have one atom that can bind to a central atom or ion. Water (H2O) and ammonia (NH3) are examples of neutral monodentate ligands. A polydentate ligand has more than one donor site. Bidentate ligands have two donor sites. Tridentate ligands have three binding sites. 1,4,7-triazaheptane (diethylenetriamine) is an example of a tridentate ligand. Tetradentate ligands have four binding atoms. A complex with a polydentate ligand is called a chelate. An ambidentate ligand is a monodentate ligand that can bind in two possible places. For example, The thiocyanate ion, SCN-, can bind to the central metal at either the sulfur or the nitrogen. 1  Article. 2  Article. 3  Article. 4  Article. 5  Article. 6  Article. 7  Article. 8  Article.
