  2. Elimination reaction - Wikipedia

    en.wikipedia.org/wiki/Elimination_reaction

    Elimination reaction of cyclohexanol to cyclohexene with sulfuric acid and heat [1] An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one- or two-step mechanism. [2] The one-step mechanism is known as the E2 reaction, and the two-step mechanism is known as the E1 reaction ...

  3. E1cB-elimination reaction - Wikipedia

    en.wikipedia.org/wiki/E1cB-elimination_reaction

    The E1cB elimination reaction is a type of elimination reaction which occurs under basic conditions, where the hydrogen to be removed is relatively acidic, while the leaving group (such as -OH or -OR) is a relatively poor one. Usually a moderate to strong base is present. E1cB is a two-step process, the first step of which may or may not be ...

  4. Porphobilinogen deaminase - Wikipedia

    en.wikipedia.org/wiki/Porphobilinogen_deaminase

    The first step is believed to involve an E1 elimination of ammonia from porphobilinogen, generating a carbocation intermediate (1). [10] This intermediate is then attacked by the dipyrrole cofactor of porphobilinogen deaminase, which after losing a proton yields a trimer covalently bound to the enzyme (2).

  5. Hammond's postulate - Wikipedia

    en.wikipedia.org/wiki/Hammond's_postulate

    Unimolecular Elimination Reaction Mechanism. An E1 reaction consists of a unimolecular elimination, where the rate determining step of the mechanism depends on the removal of a single molecular species. This is a two-step mechanism. The more stable the carbocation intermediate is, the faster the reaction will proceed, favoring the products.

  6. Evelyn effect - Wikipedia

    en.wikipedia.org/wiki/Evelyn_effect

    There are two types of elimination reactions, E1 and E2. An E2 reaction is a One step mechanism in which carbon-hydrogen and carbon-halogen bonds break to form a double bond. C=C Pi bond. An E1 reaction is the Ionization of the carbon-halogen bond breaking to give a carbocation intermediate, then the Deprotonation of the carbocation.

  8. Fumarase - Wikipedia

    en.wikipedia.org/wiki/Fumarase

    The function of fumarase in the citric acid cycle is to facilitate a transition step in the production of energy in the form of NADH. [12] In the cytosol, the enzyme functions to metabolize fumarate, which is a byproduct of the urea cycle as well as amino acid catabolism. Studies have revealed that the active site is composed of amino acid ...
