Mar 22, 2021 · Summary. Fatty acids are carboxylic acids that are the structural components of many lipids. They may be saturated or unsaturated. Most fatty acids are unbranched and contain an even number of carbon atoms. Unsaturated fatty acids have lower melting points than saturated fatty acids containing the same number of carbon atoms.

Saturated fatty acids are the simplest form of fats that are unbranched linear chains of CH2groups linked together by carbon-carbon single bonds with a terminal carboxylic acid. 1. The term ‘saturated’ is used to indicate that the maximum number of hydrogen atoms are bonded to each carbon atom in a molecule of fat. 2. The general formula for these ...
Unsaturated fatty acids are more complex fatty acids with bent hydrocarbon chains linked together by one or more carbon-carbon double bonds with a terminal carboxylic acid group. 1. The term ‘unsaturated’ indicates that the carbons atoms do not have the maximum possible hydrogen atoms bound to carbon atoms. 2. As a result, unsaturated fatty acids c...
Stearic acid
1. Stearic acid is an example of long-chained saturated fatty acids with a hydrocarbon bone of 18 carbon atoms. The scientific name of this acid is octadecanoic 2. These are mostly found in animals (30%), and plant (5%) fats and are an important component of shea butter and cocoa butter. 3. It is white in color with a mild odor and has a melting point in the range of 68-70°C. 4. Stearic acid is produced by the saponification of triglycerides in fats and oil with boiling water. 5. Stearic acid...
Palmitic acid
1. Palmitic acid is an example of long-chained saturated fatty acids with a hydrocarbon bone of 16 carbon atoms. The scientific name of this acid is hexadecanoic 2. It is naturally found in palm oil and palm kernel oil, along with other sources like butter, cheese, milk, and meat. 3. It is white in color with greasy consistency and has a melting point of 63°C. 4. Palmitic acid is produced by the process of saponification of palm oil in the presence of higher temperature water. 5. It is used i...
Linoleic acid
1. Linoleic acid is an example of polyunsaturated fatty acids that is one of the two essential fatty acids in humans. 2. It is an 18-carbon fatty acid mostly found in plant oils. 3. It is a doubly unsaturated fatty acid, also known as an omega-6 fatty acid, found mostly in plant glycosides. 4. It exists as colorless or white oil that is virtually insoluble in water. 5. It is not synthesized within the body of mammals and thus has to be taken in through diet sources. 6. Linoleic acid is used i...
Oleic acid
1. Oleic acid is an example of monounsaturated fatty acid naturally found in vegetable fats and oils. 2. Naturally, it is colorless and odorless, but the commercially made oleic acid might appear yellow. 3. Oleic acid is the most common monounsaturated fatty acid in nature, but it exists as esters instead of fatty acids or their salts. 4. It is found in high concentrations in body fats and phospholipids of the cell membrane. It is the most abundant fatty acid in the adipose tissues in humans....

Note that there are two groups of fatty acids--saturated and unsaturated. Recall that the term unsaturated refers to the presence of one or more double bonds between carbons as in alkenes. A saturated fatty acid has all bonding positions between carbons occupied by hydrogens.
Jun 25, 2024 · Saturated fats tend to stay solid at room temperature and can cause fatty deposits in blood vessels, leading to atherosclerosis ("hardening of the arteries"). By contrast, unsaturated fats stay liquid at room temperature and are less likely to clog your arteries. In addition, most unsaturated fats are derived from plant sources (like olive ...
Most are liquids at room temperature. Figure 17.2 The Structure of Saturated Fatty Acids. (a) There is a zigzag pattern formed by the carbon-to-carbon single bonds in the ball-and-stick model of a palmitic acid molecule. (b) A space-filling model of palmitic acid shows the overall straightness of a saturated fatty acid molecule.
A quick introduction to fatty acids. (A) This is the structure of stearic acid, an 18-carbon saturated fatty acid. The normal numbering system, starting with the carboxylic acid, is shown in blue ...

What is the difference between saturated and unsaturated fat?
Unsaturated ones are typically bent, unless they have a trans configuration. In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. [1]
