If there are no double bonds, then carbon will take up as many hydrogens as it can, two (three on the ends). Because there are more hydrogens bonded, they are referred to as "saturated" lipids. Unsaturated lipids have double bonds between the carbons and hydrogens. When there is a double bond, one carbon only bonds with one hydrogen - "unsaturated" lipids. The double bonds cause "kinks" in the fatty acid tails, so it is more difficult to "pack" them together. For this reason, they do not solidify at room temperature. However, saturated lipids may solidify at room temperature -- this is how you distinguish between saturated and unsaturated lipids by sight. Examples of saturated lipids (having no double bonds between carbons and hydrogens) are animal fats. "Saturated fats" is a synonym for animal fat on nutritional labels.
Fatty acids with double bonds between some of their carbons are referred to as unsaturated fatty acids. These fatty acids tend be remain in liquid form at room temperature.
Because unsaturated fatty acids have many double bonds and the atoms cannot rotate freely around those double bonds. In the saturated fatty acids, there are no double bonds (only single bonds) and so the atoms are free to rotate.
saturated fatty acids contain more carbon atoms Saturated fatty acids have single carbon-to-carbon bonds.
Fatty acids are either saturated or unsaturated. When a fatty acid is saturated it is literally saturated with hydrogen bonds. This only occurs when there are single bonds present. If there are double bonds present between the carbon atoms, less hyrdogen atoms are required and the fatty acid is said to be unsaturated. These unsaturated fats are easier to break down by the cells of your body because double bonds react more readily.
Saturated fatty acid molecules have no carbon-carbon double bonds, and all of the remaining carbon bonds are shared by hydrogen atoms, except the one in the carboxyl group, at the beginning of the chain.Unsaturated fatty acid molecules also begin with the carboxyl group, but contain one or more carbon-carbon double bonds, and may contain one or more carbon atoms with a bonding electron that remains unassociated.
Fatty acids with double bonds between some of their carbons are referred to as unsaturated fatty acids. These fatty acids tend be remain in liquid form at room temperature.
alkenes
An alkene such as propene has 1 double bond. An alkene can also have many single bonds. In Dodecene for example there are 12 carbons. Two of the carbons are linked by a double bond and all the others by single bonds. In addition, the carbon-hydrogen bonds are all single bonds too.
Fatty acids containing double bonds are unsaturated fatty acids as they still contain sp2 carbon atoms within them.
Yes organic molecules can have single bonds, double bonds and triple bonds. Larger molecules, more than two carbons, always have single bonds and may have double and triple.
12 carbons with 26 hydrogens with NO double bonds
Because unsaturated fatty acids have many double bonds and the atoms cannot rotate freely around those double bonds. In the saturated fatty acids, there are no double bonds (only single bonds) and so the atoms are free to rotate.
Saturated fats contain only single bonds between carbons, whereas unsaturated fats contain at least one double bond.
The saturated fatty acids have only single bonds between atom carbons; the chain is saturated with hydrogen atoms.
Covalent single- and double-bonds.
Susceptibility to spoilage by oxygen of fatty acids is determined by the number of double bonds in the acid's carbon chain. Molecular oxygen can attack these bonds and break the chain, forming ketones. Incidentally, naturally-occuring cis-double bonds are more susceptible than the artificial trans-fatty acids.
Unsaturated fatty acids are fatty acids that have double bonds in their long carbon chains.
