  2. Aquaporin - Wikipedia

    en.wikipedia.org/wiki/Aquaporin

    The pioneering research and subsequent discovery of water channels by Agre and his colleagues won Agre the Nobel Prize in Chemistry in 2003. [7] Agre said he discovered aquaporins "by serendipity." He had been studying the Rh blood group antigens and had isolated the Rh molecule, but a second molecule, 28 kilodaltons in size (and therefore ...

  3. Insertion reaction - Wikipedia

    en.wikipedia.org/wiki/Insertion_reaction

    Such reactions are subject to the usual parameters that affect other reactions in coordination chemistry, but steric effects are especially important in determining the stereochemistry and regiochemistry of the reactions. The reverse reaction, the de-insertion of CO and alkenes, are of fundamental significance in many catalytic cycles as well.

  4. Migratory insertion - Wikipedia

    en.wikipedia.org/wiki/Migratory_insertion

    In organometallic chemistry, a migratory insertion is a type of reaction wherein two ligands on a metal complex combine. It is a subset of reactions that very closely resembles the insertion reactions, and both are differentiated by the mechanism that leads to the resulting stereochemistry of the products. However, often the two are used ...

  5. Mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrometry

    Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions.The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio.

  6. Pressurized water reactor - Wikipedia

    en.wikipedia.org/wiki/Pressurized_water_reactor

    A pressurized water reactor (PWR) is a type of light-water nuclear reactor.PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan, India and Canada).

  7. Small interfering RNA - Wikipedia

    en.wikipedia.org/wiki/Small_interfering_RNA

    Mediating RNA interference in cultured mammalian cells. Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded non-coding RNA molecules, typically 20–24 base pairs in length, similar to microRNA (miRNA), and operating within the RNA interference (RNAi) pathway.

  8. Intercalation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Intercalation_(biochemistry)

    Intercalation induces structural distortions. Left: unchanged DNA strand. Right: DNA strand intercalated at three locations (black areas). In biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA).

  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.
