An unsaturated compound is a type of organic molecule that contains one or more double or triple bonds between carbon atoms. These bonds allow for the potential addition of more atoms, making unsaturated compounds more reactive than their saturated counterparts, which only have single bonds. Common examples include alkenes and alkynes, which are important in various chemical reactions. Unsaturated compounds are significant in many biological processes and industrial applications. For instance, fatty acids can be classified as unsaturated when they contain one or more double bonds, influencing their physical properties and health effects. Additionally, unsaturated hydrocarbons are often used in the production of plastics and fuels.
