High Quality Content by WIKIPEDIA articles! In organic chemistry, an unsaturated compound is a chemical compound that contains carbon-carbon double bonds or triple bonds such as in alkenes or alkynes. In a saturated compound these double bonds are removed by the addition of hydrogen and no multiple bonds are present. Alkanes are an example of saturated compounds. It is in this sense that fatty acids are classified as saturated or unsaturated, according to their iodine number.In a chain of carbons, such as a fatty acid, a double or triple bond will cause a kink in the chain. These kinks have macro-structural implications. Unsaturated fats tend to be liquid at room temperature, rather than solid, due to the kinks in the chain. The kinks prevent the molecules from packing closely together, forming a liquid. These fats are called oils and are present in fish and plants.
