  2. Conjugated system - Wikipedia

    en.wikipedia.org/wiki/Conjugated_system

    Cinnamaldehyde is a naturally-occurring compound that has a conjugated system penta-1,3-diene is a molecule with a conjugated system Diazomethane conjugated pi-system. In theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability.

    The Balanites aegyptiaca tree reaches 10 m (33 ft) in height with a generally narrow form. The branches have long, straight green spines arranged in spirals. The dark green compound leaves grow out of the base of the spines [7] and are made up of two leaflets which are variable in size and shape. [9]

    en.wikipedia.org/wiki/DOTA_(chelator)

    DOTA (also known as tetraxetan) is an organic compound with the formula (CH 2 CH 2 NCH 2 CO 2 H) 4. The molecule consists of a central 12-membered tetraaza (i.e., containing four nitrogen atoms) ring. DOTA is used as a complexing agent, especially for lanthanide ions. Its complexes have medical applications as contrast agents and cancer treatments.

    en.wikipedia.org/wiki/Bacterial_conjugation

    Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. [1] This takes place through a pilus. [2] [full citation needed] It is a parasexual mode of reproduction in bacteria. Escherichia coli conjugating using F-pili. These long and robust ...

    en.wikipedia.org/wiki/Cell_notation

    In electrochemistry, cell notation or cell representation is a shorthand method of expressing a reaction in an electrochemical cell.. In cell notation, the two half-cells are described by writing the formula of each individual chemical species involved in the redox reaction across the cell, with all other common ions and inert substances being ignored.

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  9. Spiro compound - Wikipedia

    en.wikipedia.org/wiki/Spiro_compound

    In organic chemistry, spiro compounds are compounds that have at least two molecular rings sharing one common atom. Simple spiro compounds are bicyclic (having just two rings). [2]: SP-0 [3]: 653, 839 The presence of only one common atom connecting the two rings distinguishes spiro compounds from other bicyclics.
