9-CIS-RETINAL Chemical Properties,Usage,Production

Chemical Properties

Pale-Yellow Solid

Uses

9-cis-Retinal is an isomer of all-trans-Retinal (R240000).

Definition

ChEBI: A retinal in which the double bond at position 9 has cis configuration, whilst the remaining acyclic double bonds have trans configuration.

Biological Activity

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.

Safety Profile

Experimental reproductive effects.When heated to decomposition it emits acrid smoke and irritating fumes.
