Retinal is a carotenoid constituent of visual pigments. It is the oxidized form of retinol which functions as the active component of the visual cycle. It is bound to the protein opsin forming the complex rhodopsin. When stimulated by visible light, the retinal component of the rhodopsin complex undergoes isomerization at the 11-position of the double bond to the cis-form; this is reversed in "dark" reactions to return to the native trans-configuration.

1. As an important signal transduction molecule in the development of the eyeball, retinaldehyde plays many important roles in the development of the vertebrate eyeball. Myopia is a developmental disease. The active expansion of the myopic eye Sclera is an important mechanism for its elongation. The ace'tal may be a messenger molecule that regulates the elongation of the experimental myopic eye, and the relationship between the occurrence and development of ace'tal and experimental myopia. Make some progress, This study reviewed the development of retinaldehyde and its nuclear receptors, the retina, choroid, scleral changes in the experimental myopia of the eyeball, and its use as a messenger molecule to transmit an elongation signal from the retina to the Sclera.2. Although smoking cessation can greatly reduce the risk of lung cancer, for 20 years, they are still twice as likely to have
the cancer as never smokers. Studies by American experts show that for such smokers, taking appropriate amounts of retinaldehyde(a derivative of vitamin A retinol and retinoic acid) daily can further effectively reduce the risk of lung cancer.
