<P> In organic chemistry, a saturated compound is a chemical compound that has a chain of carbon atoms linked together by single bonds . Saturated hydrocarbons are called alkanes . 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 . Only unsaturated compounds are those in which addition reaction can be obtained . </P> <Table> <Tr> <Td_colspan="2"> Saturated compounds </Td> </Tr> <Tr> <Td> Ethane </Td> <Td> Propane </Td> </Tr> <Tr> <Td> </Td> <Td> </Td> </Tr> <Tr> <Td_colspan="2"> 1 - Octanol </Td> </Tr> <Tr> <Td_colspan="2"> </Td> </Tr> <Tr> <Td_colspan="2"> Saturated fatty acids </Td> </Tr> <Tr> <Td_colspan="2"> </Td> </Tr> </Table>
