In [[organic chemistry]], an '''unsaturated compound''' is a [[chemical compound]] that contains carbon-carbon [[double bond]]s or [[triple bond]]s such as in [[alkene]]s or [[alkyne]]s. In a '''saturated compound''' these double bonds are removed by the addition of hydrogen and no multiple bonds are present. [[Alkane]]s are an example of saturated compounds. |

It is in this sense that [[fatty acid]]s 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. |
|||
In other unsaturated hydrocarbons, the double bond between two carbons prevents rotation of the atoms about the bond, locking them into specific structural formations. When attached atoms occupy similar positions on each carbon, they are referred to as ''[[cis]]'', and when they are on opposite sides, they are called ''[[trans]]''. Most natural hydrocarbons exist in the ''cis'' state, but artificially manufactured hydrocarbons are of ''trans''. The body lacks the enzymes to properly break down the ''trans'' configuration, which is why trans fats are viewed as dangerous and unhealthy: because they tend to build up. Unsaturated compounds of the two formations are classified as [[geometric isomers]] of one another. |
