See also: Saturation (chemistry). In organic chemistry, a saturated compound is a chemical compound that has a chain of carbon atoms linked together by single bonds. Alkanes are an example of saturated compounds.An unsaturated compound is a chemical compound that contains carbon-carbon double bonds or triple bonds, such as those found in alkenes or alkynes, respectively. Saturated and unsaturated compounds need not consist only of a carbon atom chain.They can form straight chain, branched chain, or ring arrangements. They can have functional groups, as well. It is in this sense that fatty acids are classified as saturated or unsaturated.aturated and unsaturated compounds need not consist only of a carbon atom chain.
