CAS 116-31-4: Retinal
Description:Retinal, also known as vitamin A aldehyde, is a vital organic compound with the chemical formula C20H28O. It is a derivative of vitamin A and plays a crucial role in the visual process, particularly in the function of photoreceptor cells in the retina. Retinal exists in two isomeric forms: 11-cis-retinal and all-trans-retinal, with the former being essential for vision as it binds to opsin proteins to form rhodopsin, a light-sensitive receptor. The compound is characterized by its conjugated double bond system, which contributes to its light-absorbing properties. Retinal is typically a yellowish to orange solid at room temperature and is soluble in organic solvents but less so in water. Its stability can be affected by light and oxygen, leading to isomerization or degradation. In addition to its biological significance, retinal is also studied for its potential applications in photonics and materials science due to its unique optical properties.
