They differ from saturated fats in that their chemical structure contains one or more double bonds. • Saturated fatty acids form saturated fats, while unsaturated fatty acids form unsaturated fats. National Center for Biotechnology Information. Excessive consumption of unsaturated fatty acids is responsible for decreasing the cholesterol levels in the body, sometimes less than desired. The unsaturated fatty acids found in the human body exist in the cis conformation. Unsaturated fatty acids account for about 30% of all calories required for the body. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Palmitic acid is an example of long-chained saturated fatty acids with a hydrocarbon bone of 16 carbon atoms. Save my name, email, and website in this browser for the next time I comment. Saturated fatty acids exist in the solid-state at room temperature. There are two types of fatty acids based on their number of C=C bonds; namely (a) monounsaturated fatty acids, which contain only one C=C double bond along the fatty acid chain and are found in canola, peanut, olive, avocado and cashews, and (b) polyunsaturated fatty acids, which contain two or more C=C double bonds and are found in fish, almonds and pecans. Saturated fatty acids also have low rancidity. Saturated fatty acids have only single bonds between the carbons. Jain JL, Jain S, and Jain N (2005). Having more double bonds in your unsaturated fatty acids decreases the melting point (unsaturated fats which are often used in cooking are liquid at room temperature. What is the difference between Saturated and Unsaturated Fatty Acids? Some examples of popularly known saturated fatty acids include stearic acid, palmitic acid, capric acid, lauric acid, myristic acids, etc. However,unsaturated fatty acids have one or more points of unsaturation, where hydrogen atoms are missing in the chain. • Unlike the unsaturated fatty acids, saturated fatty acids are soluble in vitamins. Based on the chemical structure of the fatty acid chain, there are two types of fatty acids present in the body; namely, saturated and unsaturated fatty acids. Stearic acid might be used as a food additive in some foods, but more important use of this fatty acid is as a lubricant or softening agent. Unsaturated fatty acids make up the oil part of lipids. Unsaturated fatty acids are divided into different groups depending on the number of double bonds present in the chain. • The sources of saturated fatty acids are animal fat, coconut oil, palm oil, whereas those of unsaturated fatty acids are most vegetable oils and fish oil. Based on the chemical structure of the fatty acid chain, there are two types of fatty acids present in the body; namely, saturated and unsaturated fatty acids. Saturated fatty acids usually have a higher melting point than their counterparts which leads to the common understanding that saturated fatty acids remain in the solid-state at room temperatures. Stearic acid is an example of long-chained saturated fatty acids with a hydrocarbon bone of 18 carbon atoms. Saturated fatty acids are the simplest form of fats that are unbranched linear chains of CH2 groups linked together by carbon-carbon single bonds with a terminal carboxylic acid. Saturated fatty makes up about 10% of all the fat required in our diet as an excess of these fats might increase the risk of heart diseases. The scientific name of this acid is hexadecanoic. Saturated fatty acids have a higher melting point. Types: Saturated fatty acids are not divided into any types. 20 Differences Between Saturated and Unsaturated fatty acids, Key Differences (Saturated fatty acids vs Unsaturated fatty acids), Read Also: Omega oxidation (ω-oxidation) of fatty acid. Saturated fats can impact your health. Designed with ❤️ by Sagar Aryal. These can add calories to your meal and weight to your waistline if you consume too much of either one, so it is best to eat them in moderation. These are stored in the liver and underneath the skin in mammals. Most common fatty acids have the chain length of 16 to 18 number of carbons. Two of the carbons are connected by a double bond, and two of the hydrogens are missing. The main sources of unsaturated fats are mostly found in plants. Saturated fatty acids are also soluble in vitamins. Unsaturated fatty acids have a lower melting point. PubChem Compound Summary for CID 445639, Oleic acid. This fatty acid is unsaturated. Poly-unsaturated fats have multiple double bonds, are even more “bent”, and have even lower melting points. Saturated fatty acids consist of unbranched carbon chains with no double bonds in it. Hydrogenation is possible in unsaturated fatty acids as the double bonds can be converted to single bonds. Besides, it is also added as a food additive as it adds texture to processed foods. If there are at least two double bonds, it is a polyunsaturated fat. Saturated fat is the type of fat in which fatty acids form single bonds, whereas unsaturated fat is the type of fat in which there is one or more double bond in the fatty acid food chain. They can be further categorized as:   Oleic acid, shown above, has just one double bond, so it is called “mono-unsaturated”. While it is well known that there are saturated and unsaturated fats, fewer people are aware that unsaturated fats are further classified into two other groups: monounsaturated fats (sometimes seen as an acronym — MUFA) and polyunsaturated fats (PUFA). Both unsaturated fat and saturated fat are equally energy-dense. Biosynthesis of oleic acid occurs within the body by dehydrogenation of stearic acid in the presence of the enzyme stearoyl-CoA 9-desaturase. It is white in color with a mild odor and has a melting point in the range of 68-70°C. Saturated fats, like butter or bacon grease, solidify at room temperature, while unsaturated fatty acids, like olive oil, tend to be liquid at room temperature. National Center for Biotechnology Information. Whereas, unsaturated fatty acids have one or more double bonds. What Is Unsaturated Fat? S. Chand and Company. Excessive consumption of saturated fatty acids might lead to heart diseases. But some saturated fatty acids are also found in vegetable sources like vegetable oil, coconut oil and peanut oil. It is found in high concentrations in body fats and phospholipids of the cell membrane. However, the … Yashoda Ramyajith Somarathna holds a B.Sc. The scientific name of this acid is octadecanoic. Types of Saturated and Unsaturated Fats. 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. Vegetable oils contain two types of polyunsaturated fatty acids linoleic acid (. This means that, without hydrogens between them, they are solid at room temperature and they have a higher melting point, requiring more energy to break the bond. Saturated fatty acids do not have any carbon-carbon double bonds. Saturated fatty acids do not get spoil quickly and are long- lasting, but unsaturated fatty acids get spoil quickly.
