What fatty acids do not have double bonds beween carbons?
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.
An omega-3 fatty acid has its first double bond on the?
The first double bond is between the third and fourth carbons from the methyl (CH3) end of the fatty acid molecule.
What type of fatty acid has double bonds?
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
A fatty acid is unsaturated if it does what?
A fatty acid is unsaturated if it contains one or more double bonds between carbon atoms in the hydrocarbon chain.
What chemical feature distinguishes a saturated fatty acid from unsaturated fatty acid?
The unsaturated ones are the ones with one or more double bonds in the carbon chain, by which they are lacking 2 H atoms per double bond as compared with the saturated fatty acid. The unsaturated ones are in general more 'healthy' with respect to possible cholesterol build up in blood vessels (cardial risks)
Is it true that Saturated fats are composed of fatty acids with several double bonded carbons?
No, saturated fats are composed of fatty acids with no double bonds between carbons. This means the carbon atoms are "saturated" with hydrogen atoms. Unsaturated fats, on the other hand, have one or more double bonds between carbons.
A fatty acid that contains a chain of 10 carbons and one double bond is termed a?
A fatty acid that contains a chain of 10 carbons and one double bond is termed monounsaturated, medium chain fatty acid. The process of adding hydrogen too an unsaturated fatty acid and creating a more solid fat is called hydrogenation.
Why is oleic acid not classified as a saturated fatty acid?
Oleic acid has one double bond in its carbon chain, making it a monounsaturated fatty acid. Saturated fatty acids have no double bonds in their carbon chain, which is why oleic acid is not classified as saturated.
How many carbons do long-chain fatty acids contain?
The long chain fatty acids generally contain between four and six carbons. This is why they generally have high boiling points.
What is the main difference between saturated and unsaturated fatty acids?
The main difference between saturated and unsaturated fatty acids is the presence of double bonds in unsaturated fatty acids. Saturated fatty acids have no double bonds in their carbon chains, while unsaturated fatty acids have one or more double bonds. This structural difference affects their physical properties and health implications.

A fatty acid tail that contains all single bonds between carbons?
Saturated fat
An essential omega 3 fatty acid with 18 carbons and 3 double bonds is called?
alpha-linoleic acid.
An omega-3 fatty acid has its first double bond on the?
The first double bond is between the third and fourth carbons from the methyl (CH3) end of the fatty acid molecule.
Suggest a reason that linoleic acid is classified as a polyunsaturated fatty acid and oleic acid is classified as a monounsaturated fatty acid?
Linoleic acid has more than one double bond in its carbon chain, making it polyunsaturated. Oleic acid has only one double bond, making it monounsaturated. The number of double bonds determines the classification of the fatty acid.
An essential fatty acid with 18 carbon and two double bonds?
This describes linoleic acid, an omega-6 fatty acid that is essential for the human body. It has 18 carbons and two double bonds, with the first double bond at the sixth carbon from the omega end of the molecule.
Why are the shapes of the lipid molecules different between saturated and unsaturated fats?
Because the unsaturated fats contains double bonds between some of the carbons, saturated fats only contain single bonds between all of the carbons. The double bonding gives the molecules a different goemetry.
