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.
Unsaturated fatty acids have double bonds in their chemical structure, while saturated fatty acids do not. This difference affects their health implications, as unsaturated fats are generally considered healthier than saturated fats due to their ability to lower bad cholesterol levels and reduce the risk of heart disease.
saturated fatty acids contain more carbon atoms Saturated fatty acids have single carbon-to-carbon bonds.
Saturated fatty acids have no double bonds and therefore no 'kinks' in their structures. These would mean that these fatty acids can pack more closely than unsaturated fatty acids and cause the membrane to be LESS fluid.
The two basic types of fatty acids are saturated and unsaturated. A fatty acid consists of a hydrocarbon chain and a carboxyl group: CH3(CH2)nCOOH Saturated fatty acids have only single bonds between the carbon atoms in the hydrocarbon chain ie the molecule is "saturated" with hydrogen atoms and no more can be added. Unsaturated fatty acids have one or more double bonds between the carbon atoms in the hydrocarbon chain. Fatty acids with a single double bond are called monounsaturated. Fatty acids with two or more double bonds are called polyunsaturated. See:http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/F/Fats.html
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.
Fatty acids can be either saturated or unsaturated. Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds.
There is no difference between saturated fatty acids and saturated fatty acids. If you meant saturated fatty acids and UNsaturated fatty acids, then the unsaturated ones are the ones with double (or, theoretically, triple) bonds in the carbon chain.
Saturated fatty acids have single carbon-to-carbon bonds (which tend to act like a rigid pole) while unsaturated fatty acids have double carbon-to-carbon bonds (which can act like hinges making the molecule flexible).
Unsaturated fatty acids have double bond or triple bonds, whereas saturated fatty acids do not.
Unsaturated fatty acids have double bonds in their chemical structure, while saturated fatty acids do not. Unsaturated fats are generally considered healthier than saturated fats because they can help lower bad cholesterol levels and reduce the risk of heart disease.
This is because it contains more saturated fatty acids then unsaturated fatty acids. Saturated fatty acids have a higher melting point then unsaturated fatty acids.
Saturated fatty acids have single carbon-to-carbon bonds (which tend to act like a rigid pole) while unsaturated fatty acids have double carbon-to-carbon bonds (which can act like hinges making the molecule flexible).
Saturated fatty acids have single carbon-to-carbon bonds (which tend to act like a rigid pole) while unsaturated fatty acids have double carbon-to-carbon bonds (which can act like hinges making the molecule flexible).
Saturated fatty acids have straight structures because their carbon chain is fully saturated with hydrogen atoms, leading to a linear conformation. In contrast, unsaturated fatty acids have double bonds that introduce kinks in the carbon chain, causing the structure to bend rather than remain straight.
Saturated fatty acids have single carbon-to-carbon bonds (which tend to act like a rigid pole) while unsaturated fatty acids have double carbon-to-carbon bonds (which can act like hinges making the molecule flexible).
Hydrogenated fatty acids.
The presence of double bonds in the carbon chain of a fatty acid determines whether it is saturated or unsaturated. Saturated fatty acids have no double bonds, while unsaturated fatty acids have one or more double bonds.
