What Is Fatty Acid Monomer? 

fatty acid monomer

Do you have an idea of fatty acid monomers? Not? Then stay connected with this article till the end. Just like the cell is the basic unit in the human body, the monomer is the basic unit of the polymer. Monomers are very tiny particles that you can not break further. Do you know? A variety of fatty acids exists in the diet of humans, in the bloodstream of humans, and in the cells and tissues of humans. Fatty acids are energy sources and membrane components. This monomer has biological activities that act to influence cell and tissue metabolism, function, and responsiveness to hormonal and other signals. Well, without delay let’s get started and learn about fatty acid monomer. 

What Is Fatty Acid Monomer? 

Fatty acid monomer is the monomer of lipids. Along with fatty acids, there is also glycerol which is a monomer of fatty acids. Fatty acids with double bonds are called ‘unsaturated fatty acids” and others are saturated fatty acid monomers. While talking about lipids, are nothing but fatty acid compounds that perform different functions in our bodies. Lipids are the part of the human cell membrane and help control what goes in and out of their cells. They assist with moving and storing energy, absorbing vitamins, and making hormones. Having too many lipids is harmful. A lipid panel can tell you if you have normal levels. 

Well, now you have that the lipid monomer is glycerol and fatty acid. Let’s take a look at some important properties of lipid monomer fatty acid and glycerol. 

Properties Of Fatty Acid Monomer 

Here are some properties of fatty acid monomers are given, 

  • Fatty acid monomers are the building blocks of the fat in the human body and in the food they eat.
  • During the digestion process, the fat is broken down into a compound called fatty acids, which can then be absorbed into the blood.
  • The molecules of the fatty acids are usually attached to each other in groups of three, forming a molecule called triglyceride.
  • Fatty acid monomers are derived from plant oils, including soybean oil, which is composed of more than 99% triglyceride molecules.
  • Fatty acids contain a straight chain of an even number of carbon atoms along with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group at the other end.
  • But, a few fatty acids have branched chains.

Fatty Acid Structure And Function 

To get a clear idea of fatty acid monomers, you should have an idea of fatty acids’ structure and function. You don’t need to be worried. Here we have mentioned all about it. 

Fatty Acid Structure 

Fatty acids are mainly composed of carbon chains containing a methyl group at one end and a carboxyl group (-COOH) at another end. The chemical formula of fatty acids is H(CH2)nCOOH, in this, ‘n’ denotes there are continuous units of this compound, and they collectively make a long chain of a polymer called Lipid. In the fatty acid structure, the methyl group is called the Omega, and the carbon atom next to the carboxyl group is called Alpha carbon, followed by the Beta-carbon, etc. fatty acid molecules have two chemically different regions namely a long hydrophobic hydrocarbon chain and a carboxyl group. 

Fatty Acid Function 

Fatty acids are very essential in the human body as they make a polymer called Lipid and it is also a building block in the cell. Also, they have highlighted their role in signal-transduction pathways, cellular fuel sources, the composition of hormones and lipids, the modification of proteins, and energy storage within adipose tissue in the form of triacylglycerols. 

Fatty acids act as a messenger, helping proteins do their work. They also start chemical reactions that help watch the growth, immune functions, reproduction, and other aspects of basic metabolism. 

Facts About Fatty Acid 

Here are some interesting facts about fatty acids. 

  • Fatty acid monomers are the building blocks of lipids
  • They comprise between 85 and 95% of the facts in the foods.
  • The polymer of fatty acids called lipids is present in and derived from both plant and animal sources.
  • The fundamental constituents of these fats are triglycerides which occupy about 90% of the fat in food and over 90% of the fat in the body.
  • Saturated fatty acids are hydrocarbon chains with only one bond between each of the carbon atoms.
  • Unsaturated fatty acids are characterized by one or more double bonds in the carbon chain.

Why Are Fatty Acids Monomers?

Monomers are smaller molecules, and when bonded together, make up polymers . -Fatty acids are the monomers for lipids , for example, and regardless of how they are bonded (as a saturated or unsaturated fat, for example), they will form lipids.

Why Are Fatty Acids Not Monomers?

Simply put, lipids are a type of fat having a glycerol molecule and a two or three fatty acid chain. Although there is always one glycerol, the number of fatty acids varies. As a result, there isn’t a monomer unit.

Are Fatty Acids Monomers Of Proteins?

Monomers are the building blocks of the four basic macromolecules of life- monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA.

What Is The Monomer And Polymer Of Fatty Acids?

Lipids’ monomers are glycerol and fatty acids. The glycerol makes the backbone of a triglyceride, a common lipid polymer. Three fatty acids make the long fatty chains of triglyceride. Each polymer of lipids is similar in that they have the same basic structures of the monomers within.


Now, you have the fatty acids polymer as well as the fatty acid monomer structure in detail. Fatty acids are composed of hydrocarbon chains terminating with carboxylic acid groups. They and their associated by-products are the primary components of lipids. The length and degree of saturation of the hydrocarbon chain are highly variable between each fatty acid and dictate the associated physical properties. Also, fatty acids are accountable for the hydrophobic properties shown by lipids as I have also described in the above article  fatty acid monomer.
