what is the difference between a saturated and unsaturated fatty acid?
51834
The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain.

In acids with only a few carbons, the acid functional group dominates and gives the whole molecule a polar character. However, in fatty acids, the non-polar hydrocarbon chain gives the molecule a non-polar character. ... There are two groups of fatty acids--saturated and unsaturated.

Unsaturated fats can be cis fats or trans fats. Cis fats are the typical form of unsaturated fat found in nature, while trans fats are made through hydrogenation. Trans fats have a similar shape to saturated fats, so many of the physical properties are the same.

A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. ... An unsaturated solution is a solution that contains less than the maximum amount of solute that is capable of being dissolved.

The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. ... Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.

Unsaturated Fats at Room Temperature The two carbons on the hydrocarbon molecules each have triple or double bonds, and hydrogens cannot saturate them. ... On the other hand, saturated fats do not have these double bonds in their fatty acid chains and are solid at room temperature.

Unsaturated fats, which are liquid at room temperature, are different from saturated fats because they contain one or more double bonds and fewer hydrogen atoms on their carbon chains. Unsaturated fats come from plants and occur in the following kinds of foods: Olives.

Fats, unsaturated and saturated are not soluble in water. ... Some are designated as SATURATED FATTY ACIDS as they have only single bond between carbons. In contrast, those that are classified a UNSATURATED, have double or even triple bonds between some carbon atoms.

These fatty acids are referred to as saturated because the hydrocarbon chain is saturated with hydrogen atoms due to the absence of double bonds. Its general formula is CnH2nO2, where there are twice as many hydrogen atoms as there are carbon atoms, and there are always two oxygen atoms.

Oils which contain mostly unsaturated fatty acids are often called 'unsaturated fats'. These include vegetable oil, olive oil, sunflower oil avocados and nuts. Fats and oils which contain mostly saturated fatty acids are often called 'saturated fats'.

Only unsaturated fats can be trans or cis fat, since only a double bond can be locked to these orientations. Saturated fatty acids are never called trans fats because they have no double bonds.

-Saturation: Saturated fatty acids have all single bonds between the carbons making them more solid at room temperature. Unsaturated fatty acids have a double bond, making them more liquid at room temperature. You just studied 19 terms!

SUMMARY Saturated fatty acids are one of the two major categories of fat. Common dietary saturated fatty acids include stearic acid, palmitic acid, myristic acid, and lauric acid.

Lipids are a larger class of molecules while fatty acids form a small part of it. Fatty acids are long chain (usually 14–20 C-atoms in length) hydrocarbons with a carboxylic acid group at one end. They can either be saturated (no double bonds) or unsaturated (one or more double bonds along the C-chain).

The saturated fatty acids are derived from both animal fats and plant oils. Rich sources of dietary saturated fatty acids include butter fat, meat fat, and tropical oils (palm oil, coconut oil, and palm kernel oil). Saturated fatty acids are straight-chain organic acids with an even number of carbon atoms (Table 2).

Saturated fatty acids (SFA) vary in chain length. Most animal fats are rich in long-chain SFA (equal or longer than 12 C), although some vegetable oils also contain significant percentages of SFA.

The fatty acids on a saturated fat have no double bonds in their hydrocarbon chains, whereas at least one fatty acid on an unsaturated fat has a double bond. Saturated fats tend to be solid at room temperature, while unsaturated fats are liquid.
