  2. Host–guest chemistry - Wikipedia

    en.wikipedia.org/wiki/Hostguest_chemistry

    Host-guest interaction has raised dramatical attention since it was discovered. It is an important field, because many biological processes require the host-guest interaction, and it can be useful in some material designs. There are several typical host molecules, such as, cyclodextrin, crown ether, et al.

    In cooperativity, the initial ligand binding affects the host's affinity for subsequent ligands. In positive cooperativity, the first binding event enhances the affinity of the host for another ligand. Examples of positive and negative cooperativity are hemoglobin and aspartate receptor, respectively. [10] General HostGuest Binding. (1.)

    For instance, the reactant concentrations must always obey the assumption that the initial concentration of the guest ([G] 0) is much larger than the initial concentration of the host ([H] 0). In the case when this breaks down, the Benesi–Hildebrand plot deviates from its linear nature and exhibits scatter plot characteristics. [ 6 ]

    The host may be either a donor or an acceptor. In biochemistry hostguest complexes are known as receptor-ligand complexes; they are formed primarily by non-covalent bonding. Many hostguest complexes has 1:1 stoichiometry, but many others have more complex structures. The general equilibrium can be written as p A + q B ⇌ A p B q

    For example, potassium permanganate oxidations can be achieved by adding a catalytic quantity of a crown ether and a small amount of organic solvent to the aqueous reaction mixture, so that the oxidation reaction occurs in the organic phase. In all these examples, the ligand is chosen on the basis of the stability constants of the complexes formed.

    If the host serves and eats breakfast a 9 o'clock, guests should be awake and ready for the day by then. If the host sleeps in past 10, guests should feel free to sleep in, too.

  9. Intercalation (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Intercalation_(chemistry)

    One famous intercalation host is graphite, which intercalates potassium as a guest. [3] Intercalation expands the van der Waals gap between sheets, which requires energy. Usually this energy is supplied by charge transfer between the guest and the host solid, i.e., redox. Two potassium graphite compounds are KC 8 and KC 24.
