The first double bond occurs after the 6th carbon atom. children'shealth Because of this, LA is sometimes referred to as the W6 EFA. Because of the four missing hydrogen atoms, LA is even more bent than Oleic Acid, giving it a melting temperature of 23 degrees F (-5C). LA is fairly unstable, reacting with light and oxygen. Now lets look at the second EFA. This is Alpha Linolenic Acid (LNA). It is an 18 carbon fatty acid with three double bonds at the 3, 6, and 9 carbon positions. LNA is missing 6 hydrogen atoms, again all from one side. Because of the first double bond occurring at the 3rd carbon atom, LNA is sometimes referred to as the W3 EFA. It is sometimes referred to as a super unsaturated fatty acid (SUFA), even though it is also poly-unsaturated. |

| Also notice that it is bent. It bends because of the opposing charges of the hydrogen atoms. If you have ever played with magnets, you have recognized that the North and South lipids poles of two magnets pull towards each other. But when you turn one of the magnets over and try to put the two North poles or the two South poles together, they lipids push apart. The same thing happens here. The hydrogen atoms carry a negative charge and repel each other. lipids Because Oleic acid is missing two hydrogen atoms on one side, the upper two hydrogen atoms push against each other and bend the fatty acid in the middle. This creates amazingly important implications. For example, Stearic acid has a melting point of 158 degrees F (70C). Oleic acid melts at 55 degrees F (13C). This is because Oleic acid molecules are more difficult to align and aggregate less easily. Linoleic Acid: With the above background information, we move to the Essential Fatty Acids (EFAs). This EFA is called Linoleic Acid (LA) and is poly-unsaturated. |
