      Retinal (all-trans-retinal) is a polyene isoprenoid chromophore, bound to proteins called opsins, and is the chemical basis of animal vision. Retinal exists in two forms, a cis and a trans isomer. On illumination with white light, the visual pigment, cis-retinal is converted to trans-retinal. This isomer must be transformed back into the cis form by retinal isomerase before it combines again with opsin (dark phase). Both isomers can be reduced to retinol (vitamin A) by a NADH-dependent alcohol dehydrogenase.
