Retinen (Retinene)

Retinene is another name for retinaldehyde. Retinaldehyde is an aldehyde that is formed by the oxidation of vitamin A (retinol). It plays an important role in the visual cycle, participating in the formation of the visual pigment rhodopsin. Retinaldehyde is part of the chromophore group of rhodopsin and, upon absorption of light, undergoes isomerization, which triggers a cascade of photochemical reactions leading to the generation of a nerve impulse. Thus, retinaldehyde is essential for normal vision.

Retinene: Main aspects and properties

Retinene, also known as retinaldehyde, is an important biological compound that plays a critical role in vision and the regulation of many physiological processes in organisms. In this article we will look at the main aspects and properties of retinene, its role in the body and its effect on vision.

Retinene is a form of vitamin A and is an integral part of the visual pigment known as rhodopsin. Rhodopsin is found in light-sensitive cells in the retina called rods and cones. When light hits rhodopsin, retinene undergoes a chemical transformation that activates an electrical signal that is sent to the brain, resulting in the formation of visual images.

It is important to note that retinene is a molecule that is capable of transitioning from one electronic state to another when it absorbs light. This property allows retinene to play a key role in vision. When photons of light hit retinene, isomerization occurs, as a result of which the conformation of the molecule changes and a signaling cascade is activated, leading to the perception of light.

In addition to its role in the visual process, retinene is also important for many other physiological functions. For example, it is necessary for the normal development of the retinal epithelium and maintenance of its health. Retinene is also involved in regulating cell growth and development, immune function, and maintaining healthy skin and mucous membranes.

One source of retinene is plant foods, in which it is present in the form of carotenoids such as beta-carotene. The body can convert these carotenoids into retinene and use it for its needs. Retinene can also be obtained from animal products such as liver, eggs and dairy products, which contain retinene precursors - vitamin A preforms.

A lack of retinene or vitamin A can lead to a variety of vision problems, including night blindness and xerophthalmia (dry eyes). Additionally, a lack of retinene can have a negative impact on immune function and overall skin health.

In conclusion, retinene plays a fundamental role in vision and the regulation of numerous physiological processes. Its ability to change from one electronic state to another upon absorption of light makes it an important component of visual pigment and enables the perception of light. In addition, retinene is significant for the development and maintenance of retinal health, immune function and skin condition. Eating a healthy diet that includes sources of retinene, such as plant foods and animal products, is an important aspect of maintaining optimal retinene levels in the body.
