Retinene (Noun)
Meaning
Either of two yellow to red retinal pigments formed from rhodopsin by the action of light.
Classification
Nouns denoting substances.
Examples
- Retinene is a pigment that plays a crucial role in the visual cycle of the eye, helping to regenerate rhodopsin in the retina.
- The formation of retinene from rhodopsin is a key step in the process of visual adaptation to changes in light levels.
- Studies have shown that retinene is essential for the proper functioning of the rod cells in the retina, which are responsible for peripheral and night vision.
- Retinene is a critical intermediate in the visual cycle, as it is converted back into rhodopsin through a series of enzyme-catalyzed reactions.
- The structure of retinene has been extensively studied using techniques such as nuclear magnetic resonance spectroscopy and X-ray crystallography.
