Do you know about carb monomers? If you don’t know about it, then read this article till the end. Probably you all know that carbs are one of the essential factors in the human diet. Fortunately, your body is capable of breaking down carbs into glucose. As you all know that our body can not digest glucose, so we need to consume it in the form of starch or carb. Glucose is the main source of energy for your body’s cells, tissues, and organs. Carb is popularly known as Carbohydrates, it is a sugar molecule along with proteins and fats, and is one of three main nutrients found in food and drinks. Let’s have a look at the carb monomer

What Is Carb Monomer? 

Carb monomer is called monosaccharides, which is a simple sugar and a basic building block of carbohydrates polymer. Simple sugar is used by the cells of living things to store and produce energy. A monosaccharide is a type of monomer, a molecule capable of combining with other similar molecules to create more complex polymers.  

While talking about carb monomer structure, it has a chemical formula of CnH2nOn. In other words, they are created out of the hydroxyl group which is OH as well as a carbonyl group which is C=O. 

There are several types of monosaccharides or carb monomer examples, each defined by how many carbon atoms the molecules have. For example, a diose molecule has two carbon atoms, a triose molecule has three, a tetrose has four and fructose has six. The bond between monosaccharides creates carbohydrates, which are referred to as either polysaccharides or oligosaccharides. If an oligosaccharide has just two monosaccharides composing it, it is called a disaccharide. The combination of more than 20 monosaccharides creates a polysaccharide, a complex carbohydrate. 

Now, let me tell you some unique properties of complex carb monomers.

Properties Of Carb Monomer 

Here are the properties of carb monomer, 

  • Monosaccharides are soluble in water. 
  • Carb monomers can not be broken down into simple sugars. 
  • They show the phenomenon of stereo-isomerism. 
  • They are sweet in taste. 
  • Monomers of carbohydrates are reducing in nature. 
  • Monosaccharides are colorless and crystalline compounds. 
  • D-glucose and L-glucose are mirror images of each other. 
  • The presence of asymmetric carbon atoms in a compound gives rise to the foundation of an isomer of that compound.

Carb Structure And Function 

Carb structure and function are, 

Carb Structure 

Carbohydrates are hydrates of carbon and have a generic structure with the chemical formula of C(n)H(2n)O(n). It is made up of monosaccharides, so these can consist of 3-carbon moieties, 4-carbon units, 5-carbon moieties, and 6-carbon moieties. 

Depending on the number of molecules of sugar in the compound, carbohydrates can be classified as monosaccharides, one unit of sugar and second disaccharide, two monosaccharides, third oligosaccharide, three to fifteen monosaccharides, and polysaccharides, large polymers of simple sugars. 

Carb Function 

Carbs are vital at every stage of life. It is the primary source of energy and the brain’s preferred energy source. Carbs are broken down by the body into glucose, which is a type of sugar. Glucose is used as fuel by your body’s cells, tissues, and organs.   

Facts About Carb 

The facts about carbs are, 

  • In your body, the brain is the only carbohydrate-dependent organ. 
  • Our brain exclusively uses glucose, a basic sugar carb, to function. Since your brain cells need twice the energy of any other cells in your body gives the man some dang glucose! 
  • The lactose in milk and other dairy products is a disaccharide, which means it is a sugar, which means it’s a carb. 
  • Carbohydrates are a backbone of a carbon backbone with hydrogen and oxygen molecules attached. 
  • Carbo means carbon and hydrates mean water.

What Monomer Do Carbs Break Down Into?

Thus, a monosaccharide behaves as a monomer of carbohydrates and polysaccharides are polymers of carbohydrates.

What Type Of Bond Is In Carbs?

Glycosidic bond

Carbohydrates are made up of monosaccharides linked together into polysaccharide chains by a type of covalent bond known as a glycosidic bond.

What Is The Bond Between Two Monomers Called?

The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”

What Happens When Two Monomers Are Joined Together?

The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

Is Starch A Carb Monomer?

Summary. A polysaccharide is a complex carbohydrate polymer formed from the linkage of many monosaccharide monomers. One of the best known polysaccharides is starch, the main form of energy storage in plants.

What Is The Best Function Of Carbohydrates?

Carbohydrates provide the body with glucose, which is converted to energy used to support bodily functions and physical activity.

What Are The 5 Monomers Of Carbohydrates?

Carbohydrate monomers are monosaccarides or simple sugars so glucose, fructose, galactose, lactose and maltose. Table sugar is a combination (disaccaride) of fructose and glucose, lactose and galactose are the sugars found in milk and and maltose is found in breads.


Above, you have learned about the monomer of carbohydrates in detail, including its structure and function. Monosaccharide which is a basic unit of carbohydrates can not be hydrolyzed further to give a simple unit of polyhydroxy aldehyde or ketone is called a monosaccharide. Carbohydrates examples are cookies, potatoes, popcorn, milk, beans, bread, cherry pie, etc. two monosaccharides are connected together to make a disaccharide. Oligosaccharides are not discussed often in high school biology, but they are chains of three to nine monosaccharides. This was all about carb monomer.
