Insoluble in water, soluble in ethanol, chloroform, cyclohexane, petroleum ether and oil. It was originally isolated from the retina, and then produced by the oxidative breakdown of β-carotene. Its physiological effects are related to vision, and it is generally believed that it can cause rapid cis-trans isomerization under the action of light [1]. Retinaldehyde is the prosthetic group of rhodopsin. In visual cells, 11-cis retinal and opsin form visual pigment. After 11-cis retinal absorbs light, it is isomerized into all-trans retinal, which changes the conformation of rhodopsin and initiates the effect on the brain. Nerve impulses to 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.
