What Are Saturated and Unsaturated Fatty Acids? And What Does "Omega" Mean?

!±8± What Are Saturated and Unsaturated Fatty Acids? And What Does "Omega" Mean?

For the most part, the length of greasy acids may differ by as much as twenty carbon elements atoms or so. If a fatty acid (f. a.) has four carbon elements atoms or fewer, it is referred to as a short-chain greasy acid. On the other hand, if a fatty acid chain has six to twelve or higher than twelve carbon elements atoms, it will be known to like a medium-chain fatty acid or a long-chain f. a., respectively.

Often, fatty acids with twenty or even more carbon elem. atoms are referred to as very-long-chain fatty acids. Most fatty acids in nature have an even number of carbons, but some f. a. do certainly have an odd number of carbons. Greasy acids can differ in their degree of saturation.

Saturation refers to whether all of the carbon atoms in between the end carbons are associated to two atoms of hydrogen. If this is the situation, then the carbons are saturated with hydrogen and that particular f. a. will be known as a saturated fatty acid (SFA).

Nevertheless, if, at one or more points, adjacent carbon elements atoms are bonded to only a single hydrogen atom every, the f. a. would then be an unsaturated greasy acid: to only one hydrogen atom every, the carbon elements atoms should relationship to each other twice.

Chemists call this a double relationship and if a f. a. has only one increase relationship, it's known to as a monounsaturated f. a. (MUFA). Meanwhile, if there's a lot more than one double relationship, then it is a polyunsaturated fatty acid (PUFA). Simply because f. a. may differ significantly, experts will indicate the quantity of carbons and increase bonds in a f. a.

For example a 18:3 greasy acid will probably be 18 carbons long and have 3 increase bonds. Experts also use omega system to indicate exactly where increase bonds are inside a f. a. It functions like this. If a f. a. is linked to glycerol, the second carbon elements closest to the link is referred to as the alpha (α) carbon.

Meanwhile, the carbon elements furthest from the linkage with glycerol is known as the ω (ω) carbon. The ω system is based on the Greek alphabet. Alpha is the very first letter of the alphabet and omega is the last. No matter how many carbons are in your greasy acid chain, these carbon elements atoms will usually be addressed in this manner.

Looking at a fatty acid not associated to glycerol, the alpha carbon elements will be the very first carbon atom adjacent to the carbon elements bonded to two atoms of oxygen. To show position from the first double relationship we count the quantity of carbons to the very first carbon of the first increase relationship from the ω finish.

For instance, if the very first double relationship begins in the third carbon atom in, it is definitely an omega-3 (ω-3) greasy acid. Likewise, when the very first increase relationship seems in the sixth or the ninth carbon atom in, these would be ω-6 and ω-9 fatty acids, respectively.

For the most part, when addressing polyunsaturated fatty acids, we specify only the position from the first increase relationship because subsequent double bonds seem to happen in series right after one saturated carbon elements atom.
