All-trans-retinal (Retinaldehyde; NSC-626581; Retinal A; NSC-122757; Vitamin A aldehyde) is one of the major vitamin A metabolites in the retina. It is an oxidized form of retinol, which is a corotenoid component of the visual pigments. In physiological conditions, all-trans-RAL is regenerated to the visual chromophore, 11-cis-retinal.
