The 17 pages that link to Retinal, each with the reason it gives.

• Conjugated systemBroader topic: Light-driven changes in retinal’s conjugated chain initiate visual signaling.

• Cis–trans isomerismRelated: Its photoisomerization initiates the visual response in vertebrate photoreceptors.

• AldehydeBroader topic: Its aldehyde group is central to the light-driven shape change in visual pigments.

• ChromophoreBroader topic: Its chromophore isomerizes after absorbing a photon, initiating vision.

• Vitamin ABroader topic: Its light-triggered shape change starts the visual signal in the retina.

• Photoreceptor cellRelated: Its light-driven isomerization starts visual signaling in many animal photoreceptors.

• Geometric isomerismRelated: Light-driven geometric isomerization initiates the visual signaling cycle.

• Rod cellRelated: Its light-triggered shape change activates rhodopsin in rod cells.

• E–Z notationBroader topic: Light converts retinal between configurations at a double bond, initiating visual signaling.

• Beta-caroteneBroader topic: Enzymatic cleavage of beta-carotene can produce retinal, a direct precursor to other forms of vitamin A.

• OpsinRelated: Light converts opsin-bound 11-cis-retinal to all-trans-retinal, triggering opsin activation.

• RhodopsinRelated: Its light-driven shape change is the first molecular event in rhodopsin activation.

• Vitamin A deficiencyRelated: Reduced retinal availability impairs rhodopsin regeneration and dim-light vision.

• IsomerizationRelated: Its photoisomerization initiates the visual signaling process in vertebrate photoreceptors.

• RetinoidRelated: Its conversion connects the visual and signaling branches of vitamin A biology.

• RetinolRelated: Retinol is oxidized to retinal, the light-sensitive form used in the visual cycle.

• AzobenzeneCompared with: Retinal shows how biological systems use photoisomerization with a different molecular scaffold.
