  • During the reaction, dehydrogenation occurs, leading to the production of energy as hydrogen is removed from glucose.

Examples

  • The enzyme dehydrogenation helps convert alcohol into acetaldehyde, which is an important step in metabolism.

  • Moreover, complete dehydrogenation of dissociating CH4 could result from a reaction with the surface O species originating from the dissociation of CO2 or secondary H2O product 27, 28.

  • In the above mechanism, reducing-agent dehydrogenation on the surface is the kinetic limiting step.

    Academic text (1998)
  • In biochemistry, the process of dehydrogenation removes hydrogen atoms from molecules, playing a crucial role in cellular respiration.

Morphology

dehydrogenation = hydrogenation (semi-transparent) = de + hydrogen + ation

For someone who knows 'hydrogenation', adding 'de-' clearly signals the reverse chemical process, namely removal of hydrogen.

Etymology

Dehydrogenation has two clear parts: de- meaning 'remove' and hydrogen, the small atom that helps make water ('hydro' = 'water'). So dehydrogenation simply means the process of taking hydrogen away from a molecule.
