  2. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    Demethylation (the transfer of the methyl group to another compound) is a common process, and reagents that undergo this reaction are called methylating agents. Common methylating agents are dimethyl sulfate, methyl iodide, and methyl triflate. Methanogenesis, the source of natural gas, arises via a demethylation reaction. [8]

    In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team.

  4. Triatomic hydrogen - Wikipedia

    en.wikipedia.org/wiki/Triatomic_hydrogen

    Triatomic hydrogen or H 3 is an unstable triatomic molecule containing only hydrogen.Since this molecule contains only three atoms of hydrogen it is the simplest triatomic molecule [1] and it is relatively simple to numerically solve the quantum mechanics description of the particles.

  5. List of carboxylic acids - Wikipedia

    en.wikipedia.org/wiki/List_of_carboxylic_acids

    The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.

  6. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. The substance (or substances) initially involved in a chemical reaction are called reactants or reagents .

  7. List of reagents - Wikipedia

    en.wikipedia.org/wiki/List_of_reagents

    Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs." [1] Some reagents are just a single element. However, most processes require reagents made of chemical compounds. Some of the most common ones used widely for specific reactive functions are ...

  8. Dehydration reaction - Wikipedia

    en.wikipedia.org/wiki/Dehydration_reaction

    The conversion of ethanol to ethylene is a fundamental example: [3] [4] CH 3 CH 2 OH → H 2 C=CH 2 + H 2 O. The reaction is accelerated by acid catalysts such as sulfuric acid and certain zeolites. These reactions often proceed via carbocation intermediates as shown for the dehydration of cyclohexanol. [5] Some alcohols are prone to dehydration.

  9. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.
