Nota de alcance: Diterpeno derivado del carotenoide VITAMINA A que actúa como el componente activo del ciclo visual. Es el grupo prostético de la RODOPSINA (es decir, está unido covalentemente a la OPSINA DE LOS BASTONES como 11-cis-retinal). Cuando es estimulada por la luz visible, la rodopsina transforma este isómero cis del retinal en el isómero trans (11-trans-retinal). Esta transformación endereza la curvatura de la molécula de retinal y provoca un cambio en la forma de la rodopsina que desencadena el proceso visual. Una serie de reacciones catalizadas por enzimas que requieren energía convierten el 11-trans-retinal de nuevo en el isómero cis.

Nota de alcance: A diterpene derived from the carotenoid VITAMIN A which functions as the active component of the visual cycle. It is the prosthetic group of RHODOPSIN (i.e., covalently bonded to ROD OPSIN as 11-cis-retinal). When stimulated by visible light, rhodopsin transforms this cis-isomer of retinal to the trans-isomer (11-trans-retinal). This transformation straightens-out the bend of the retinal molecule and causes a change in the shape of rhodopsin triggering the visual process. A series of energy-requiring enzyme-catalyzed reactions convert the 11-trans-retinal back to the cis-isomer.
