9-cis-Retinal is an isomer of all-trans-Retinal (R240000).
ChEBI: A retinal in which the double bond at position 9 has cis configuration, whilst the remaining acyclic double bonds have trans configuration.
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.
