(ret'i-nal'dĕ-hīd),
Retinol oxidized to a terminal aldehyde; retinal; a carotene released (as all-trans-retinal) in the bleaching of rhodopsin by light and the dissociation of opsin in the vision cycle.

In addition, Air-CCAPR1-Like[DELTA]105 incubated with 11-cis retinal appears to possess a bistable nature, as demonstrated by the sinusoidal shape of spectrum 1, complementary to spectrum 2 (Fig.
The mutants were tested with the chromophore that gave the best result for each of the two GCPRs: 11-cis retinal for Air-CCAPR1-Like[DELTA]105 and all-trans retinal for Air-AAR1-Like[DELTA]58.
Other studies using the same expression system detected no responses in non-injected oocytes after incubation with 11-cis retinal (5).
