Vitamin A aldehyde, also called retinal, is the closest component to A acid. It is produced by the oxidative cleavage of β-carotene. Reduction to obtain retinol, oxidation to obtain retinoic acid. Retinaldehyde is the prosthetic group of rhodopsin. Visual Micro Chemicalbook Intracellular 11-cis retinal and opsin form visual pigment, 11-cis retinal isomerizes into all-trans retinal after absorbing light, which changes the conformation of rhodopsin and initiates The nerve impulses in the brain to form vision.
