  2. Wöhler synthesis - Wikipedia

    en.wikipedia.org/wiki/Wöhler_synthesis

    Wöhler demonstrated the reaction in his original publication with different sets of reactants: a combination of cyanic acid and ammonia, a combination of silver cyanate and ammonium chloride, a combination of lead cyanate and ammonia and finally from a combination of mercury cyanate and cyanatic ammonia (which is again cyanic acid with ammonia).

  3. Friedrich Wöhler - Wikipedia

    en.wikipedia.org/wiki/Friedrich_Wöhler

    Wöhler has also been regarded as a pioneering researcher in organic chemistry as a result of his 1828 demonstration of the laboratory synthesis of urea from ammonium cyanate, in a chemical reaction that came to be known as the "Wöhler synthesis". [5] [20] [21] Urea and ammonium cyanate are further examples of structural isomers of chemical ...

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...

  5. Wolff–Kishner reduction - Wikipedia

    en.wikipedia.org/wiki/Wolff–Kishner_reduction

    The Wolff–Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into methylene groups. [1] [2] In the context of complex molecule synthesis, it is most frequently employed to remove a carbonyl group after it has served its synthetic purpose of activating an intermediate in a preceding step.

  6. Biological thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Biological_thermodynamics

    Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy.

  7. Bioorthogonal chemistry - Wikipedia

    en.wikipedia.org/wiki/Bioorthogonal_chemistry

    Reaction biocompatibility: Reactions have to be non-toxic and must function in biological conditions taking into account pH, aqueous environments, and temperature. Pharmacokinetics are a growing concern as bioorthogonal chemistry expands to live animal models.

  8. Autoxidation - Wikipedia

    en.wikipedia.org/wiki/Autoxidation

    It is also an important concept in both industrial chemistry and biology. [4] Autoxidation is therefore a fairly broad term and can encompass examples of photooxygenation and catalytic oxidation . The common mechanism is a free radical chain reaction , where the addition of oxygen gives rise to hydroperoxides and their associated peroxy ...

  9. Bioenergetics - Wikipedia

    en.wikipedia.org/wiki/Bioenergetics

    Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
