Saturated and unsaturated compounds A saturated compound is a chemical compound (or ion) that resists addition reactions, such as hydrogenation, oxidative addition, and the binding of a Lewis acids and bases, Lewis base. The term is used in many contexts and classes of chemical com ...

saturated fatty acid In chemistry, in particular in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, ...

Unsaturated fat An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is Monounsaturated fat, monounsaturated if it contains one double bond, and polyunsaturated fat, polyunsaturated i ...
