  2. Dehydration reaction - Wikipedia

    en.wikipedia.org/wiki/Dehydration_reaction

    The classic example of a dehydration reaction is the Fischer esterification, which involves treating a carboxylic acid with an alcohol to give an ester RCO 2 H + R′OH ⇌ RCO 2 R′ + H 2 O Often such reactions require the presence of a dehydrating agent, i.e. a substance that reacts with water.

  3. Condensation reaction - Wikipedia

    en.wikipedia.org/wiki/Condensation_reaction

    Condensation reactions likely played major roles in the synthesis of the first biotic molecules including early peptides and nucleic acids. In fact, condensation reactions would be required at multiple steps in RNA oligomerization: the condensation of nucleobases and sugars, nucleoside phosphorylation, and nucleotide polymerization. [6]

  4. Carbon snake - Wikipedia

    en.wikipedia.org/wiki/Carbon_snake

    The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar ( sucrose ) performs a degradation reaction which changes its form to a black solid-liquid mixture . [ 1 ]

  5. Shiina macrolactonization - Wikipedia

    en.wikipedia.org/wiki/Shiina_macrolactonization

    All of the processes of Shiina macrolactonization consist of reversible reactions, with the exception of the last cyclization step.At the first stage of the reaction, mixed anhydride (MA) is produced quickly under mild conditions; at the second stage, a faster cyclization of the MA prevents an increase in MA concentration.

  6. Fischer oxazole synthesis - Wikipedia

    en.wikipedia.org/wiki/Fischer_oxazole_synthesis

    Another useful example is the one pot two-step synthesis of halfordinol, a parent compound for Rutaceae alkaloids. The initial steps follow the Fischer oxazole synthesis, although the acid-catalyzed cyclization occurs in two steps rather than one, which ensures the formation of the di-chloro intermediate, preventing formation of the regioisomer ...

  7. Neutral fat - Wikipedia

    en.wikipedia.org/wiki/Neutral_fat

    Neutral fats, also known as true fats, are simple lipids that are produced by the dehydration synthesis of one or more fatty acids with an alcohol like glycerol. Neutral fats are also known as triacylglycerols, [1] these lipids are dense as well as hydrophobic due to their long carbon chain and are there main function is to store energy ...

  8. Martin's sulfurane - Wikipedia

    en.wikipedia.org/wiki/Martin's_sulfurane

    The compound is a reagent in organic synthesis. One application is for the dehydration of a secondary alcohol to give an alkene: [2] RCH(OH)CH 2 R' + Ph 2 S[OC(CF 3) 2 Ph] 2 → RCH=CHR' + Ph 2 SO + 2 HOC(CF 3) 2 Ph Mechanism of the dehydration using Martin's sulfurane.

  9. Amphibolic - Wikipedia

    en.wikipedia.org/wiki/Amphibolic

    Anabolism has two classes of reactions. The first are dehydration synthesis reactions; these involve the joining of smaller molecules together to form larger, more complex molecules. These include the formation of carbohydrates, proteins, lipids and nucleic acids.
