Record 3 2003-11-06

English

Subject field(s)
  • Biological Sciences
DEF

Substituted benzoquinone ... that plays a role in the respiratory electron transport chain, where it receives hydrogen or electrons from a flavoprotein and is reduced to a quinol, which then reduces the next member of the chain (a cytochrome).

CONT

In the respiratory chain ..., the simplest of the electron carriers is a small hydrophobic molecule known as ubiquinone, or coenzyme Q. Ubiquinone can pick up or donate either one or two electrons, and it temporarily picks up a proton from the medium along with each electron that it carries.

OBS

CoQ is abbreviation for coenzyme Q.

French

Domaine(s)
  • Sciences biologiques
DEF

Quinone mitochondriale intervenant dans la chaîne respiratoire.

CONT

Les ubiquinones sont universellement répandues, comme leur nom l'indique, et on les trouve surtout dans les mitochondries animales et végétales où elles jouent un rôle important dans le système transporteur d'électrons. [...] La plastoquinone a une structure très voisine et participe au transport des électrons dans les chloroplastes.

OBS

CoQ est une abréviation de coenzyme Q.

Spanish

Campo(s) temático(s)
  • Ciencias biológicas
DEF

Derivado de la 2-3-dimetoxi 5-metil-1, 4-benzoquinona. Funciona como transportador de electrones en sistemas procarióticos y eucarióticos.
