9-cis-Retinal has been used for visual pigment regeneration.[1]
Biochem/physiol Actions
Retinal, retinol and retinoic acid are the aldehyde, alcohol and acid forms of vitamin A. The retinoids exist as many geometric isomers due to the unsaturated bonds in the aliphatic chain. 9-cis retinal is a natural ligand (chromophore) of the vertebrate rod visual pigment. 9-cis retinal is used in studies on the mechanisms of visual function.

The dynamics of the photoisomerization of a model protonated Schiff base of 9-cis retinal in isorhodopsin is investigated using nonadiabatic molecular dynamics simulation combined with ab initio quantum chemical calculations on-the-fly. The quantum chemical part is treated at the complete-active
The key role of vitamin A in embryonal development is reviewed. Special emphasis is given to the physiological action of retinoids, as evident from the retinoid ligand knockout models. Retinoid metabolism in embryonic tissues and teratogenic consequences of retinoid administration

Retinal is the natural ligand (chromophore) of the vertebrate rod visual pigment. It occurs in either the 11-cis (rhodopsin) or the 9-cis (isorhodopsin) configuration. In its evolution to a G protein coupled photoreceptor, rhodopsin has acquired exceptional photochemical properties. Illumination

The nuclear hormone receptors constitute a large family of transcription factors. The binding of the hormonal ligands induces nuclear receptors to assume a configuration that leads to transcriptional activation. Recent studies of retinoic acid and thyroid hormone receptors revealed that
