: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.

CAS:<p>Retinylaldehyde is a derivative of vitamin A that is important for visual health. It is an inhibitor of the chloride channel, which may be due to its ability to inhibit alcohol dehydrogenase and polymerase chain reaction (PCR). Retinylaldehyde has been shown to have a high affinity for nuclear DNA and can bind to guanine nucleotide-binding protein (G protein) in neural cells. This activity leads to chronic cough in mice. Retinylaldehyde also has been shown as having significant up-regulation in human monocytes when exposed to toll-like receptor ligands. The role of retinylaldehyde in the immune system is not fully understood, but it may play a role in modulating the response to bacterial infection by altering the production of cytokines such as interleukin-1β (IL-1β) and tumor necrosis factor alpha (TNFα).</p>Formula:C20H28OPurity:Min. 98 Area-%Color and Shape:PowderMolecular weight:284.44 g/mol
