polüenid

Polüenid is a term used in organic chemistry to describe a class of organic compounds characterized by the presence of multiple carbon-carbon double bonds within their structure. These double bonds are typically separated by at least one single bond, but in some cases, they can be conjugated, meaning they alternate with single bonds. The specific arrangement and number of these double bonds determine the chemical and physical properties of the polyenide.

Polyenides can be found in various natural products, including pigments and vitamins. For example, carotenoids, a group of pigments responsible for many of the yellow, orange, and red colors in plants and animals, are polyenides. Vitamin A and its derivatives also contain polyenide structures. In synthetic chemistry, polyenides are important building blocks for polymers and other complex organic molecules. The reactivity of the double bonds in polyenides allows them to participate in a wide range of chemical reactions, such as addition reactions and polymerization. Their study is crucial for understanding biological processes and for developing new materials.
