Retinal, also known as vitamin A aldehyde, is an oxidized derivative of retinol with a molecular formula of C20H28O. Orange crystals. There are six known stereoisomers, of which the all-trans form is the most stable. The melting point is 61~64°C. Insoluble in water, soluble in ethanol, chloroform, cyclohexane, petroleum ether and oil. Originally isolated from the retina, it is produced by oxidative cleavage of β-carotene. Its physiological effects are related to vision, and it is generally believed that it can cause a rapid cis-trans isomerization reaction under the action of light. Retinaldehyde is the prosthetic group of rhodopsin. 11-cis-retinal and opsin in visual cells form visual pigment, 11-cis-retinal isomerizes to all-trans-retinal after absorbing light, which changes the conformation of rhodopsin and initiates the stimulation of the brain. Nerve impulses that form vision. During the decomposition and resynthesis of rhodopsin, a part of retinal is consumed, which is mainly supplemented by vitamin A in the blood.
