Example of Carbohydrates: Your Essential Guide

When you hear the word carbohydrates, what comes to mind? Pasta, rice, sugar… they’re all easy to picture, right? I’m sure most people can also name a few more carbohydrate types. For example, beans, flour, and squashes are all healthy carbohydrate foods (and also commonly known).

But how about amylose or pectin; do these ring any bells? They’re classified as carbohydrates too. And not only does this group of macronutrients consist of complex and simple carbs – there are other subcategories as well. Below is an extensive (yet simple) list of different kinds of carbohydrates with a short description and examples.

What is Carbohydrates

Carbohydrates are a type of macronutrient. Macronutrients are the nutrients that provide your body with energy, which is used to keep your organs functioning. Carbohydrates are found in plant-based foods, such as fruits and vegeta andins. Carbohydrates can also be added to food through artificial sweeteners or refined sugars.

Formation of Carbohydrates

Carbohydrates are organic compounds that contain carbon, hydrogen, and oxygen. Carbohydrates include sugars (sucrose, glucose, fructose), starches (amylose, amylopectin), cellulose, and gums. Some carbohydrates comprise a single monosaccharide unit (glucose or fructose), while others are combinations of two or more monosaccharide units linked together.

Types of Carbohydrates

Types of Carbohydrates

There are two main types of carbohydrates: simple and complex Carbohydrates. But another type of Carbohydrate is resistant starch.

Simple carbohydrates include sugars and starches that are easily digested in the body. They include table sugar, fructose (fruit sugar), lactose (milk sugar), maltose (malt sugar), and glucose (blood sugar).

Complex carbohydrates are made up of many simple sugars linked together. They have a low glycemic index (GI), meaning they do not cause sudden increases in blood glucose levels. The most common complex carbohydrate is starch in bread, cereals, rice, pasta, and potatoes.

Resistant starch is an indigestible carbohydrate that passes through the digestive system unchanged and is sent off to your large intestine, which acts as a prebiotic by fermenting bacteria.

Metabolism of Carbohydrates

Metabolism of Carbohydrates

Carbohydrates are a type of dietary macronutrient that provides your body with energy. Because the body breaks down carbohydrates into glucose, they are the primary fuel source for your brain, red blood cells, and many other organs.

The process of metabolizing carbohydrates begins in the mouth, broken down into simple sugars with the help of saliva enzymes. After being swallowed, these sugars continue to be digested in the stomach and small intestine. The digestive enzymes that break down carbohydrates include amylase (which converts starch), maltase (which breaks down maltose), and lactase (which breaks down lactose).

Once these sugars enter the bloodstream, they are transported to various tissues throughout your body, which can be used as an energy source or stored as glycogen for later use.

Importance of Carbohydrates

Carbohydrates are one of the most important macronutrients. They’re found in grains, vegetables, fruits, and dairy products. Carbohydrates provide energy to the body, help you maintain healthy blood glucose levels, and prevent fatigue. Eating enough carbohydrates can help you maintain weight, reduce your risk of type 2 diabetes and improve your overall health.

Carbohydrate foods also contain fiber, which helps you feel full longer and helps control blood sugar levels. Fiber-rich foods include whole grains, beans, fruits, and vegetables.

The USDA recommends eating about 130 grams of carbohydrates daily for a healthy diet.

Different Forms of Carbohydrates

Different Forms of Carbohydrates

Carbohydrates are energy-yielding nutrients that can be categorized into three main forms: monosaccharides, disaccharides, and polysaccharides.


Monosaccharides are the simplest form of carbohydrate. They consist of a single sugar molecule. Monosaccharides include glucose, fructose, and galactose.


Disaccharides are formed when two monosaccharides bond together. Common examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose) and maltose (glucose + glucose).


Oligosaccharides are a type of carbohydrate that is made up of 3 to 10 monosaccharide units. The most common types of oligosaccharides are galactose and glucose, which are both sugars.


Polysaccharides are complex carbohydrates made up of many monosaccharide units bonded together. Examples of polysaccharides include starch and glycogen.

Useful Carbohydrates

Useful Carbohydrates

Useful carbohydrates are a type of carbohydrate that your body needs to function properly. They are found in fruits, vegetables, legumes, beans, and whole grains.

The difference between useful carbohydrates and other carbohydrates is that they do not raise your blood sugar level as much. They also have less effect on insulin production than other types of carbohydrates.

Bad Carbohydrates

Bad Carbohydrates

Carbohydrates are a crucial source of energy for your body. But not all carbs are created equal. Some carbohydrates are good for you, and some are bad for you.

Bad carbohydrates are the foods that you should try to reduce in your diet. They are high on the glycemic index, and they cause your blood sugar levels to spike, which can lead to increased fat storage in the body. It would be best if you also avoided bad carbohydrates to lose weight and maintain a healthy lifestyle.

There are two types of bad carbohydrates: simple and complex. Simple carbohydrates are found in foods like candy, chocolate, soda, white bread, pasta, and many processed foods such as cookies and cakes. Complex carbohydrates are found in whole grains such as brown rice, quinoa, and bulgur wheat.

The difference between complex and simple carbohydrates is their chemical structure: simple carbohydrates contain one molecule that breaks down into glucose very easily, whereas complex carbs have several molecules that break down into glucose more slowly than simple carbs.

Example of Carbohydrates

Some Example of Carbohydrates

Carbs are one of the three macronutrients, along with protein and fat. Carbs are a primary energy source for your body and can be found in various foods. Some examples of carbohydrates include:

Simple Carbohydrates

A. Monosaccharides


Arabinose is a simple carbohydrate found in plants’ cell walls. It can be broken down into glucose, xylose, and galactose. It is also called galactooligosaccharides.


Allulose is another type of simple carbohydrate that has been used to sweeten foods and beverages for about 40 years now. It comes from allooligosaccharide, which is made by hydrolyzing sucrose to form oligosaccharides.


Fructose is also a simple carbohydrate that comes from fruit and honey, but it’s also found in some vegetables like carrots and beets and some processed foods like high fructose corn syrup (HFCS).


Galactose is a simple carbohydrate found in milk, berries, and vegetables. It can be used as an alternative sweetener to sugar.


Glucosamine is a simple carbohydrate found in many foods, including animal products such as meat and fish. It can also be taken as a dietary supplement to help with joint pain.


Glucose is a simple carbohydrate found naturally in honey and fruit juices. It’s commonly used as a sweetener in processed foods like candy bars, sodas, and baked goods because it tastes sweet without calories!


Mannose is a monomer of glucose found in the nucleotide backbone of DNA. It is also used as an energy source by cells, though it’s not as prevalent as other simple carbohydrates.


N-acetylgalactosamine is another monomer of glucose found in mucus and glycoproteins like collagen. This carbohydrate is also important for nerve function and blood pressure regulation.


Ribose is a monomer of both glucose and ribonucleic acid (RNA). It can be found in RNA but not DNA, where it’s used to build RNA chains that make up the genetic code we know today as life on earth.”


Rhamnose is a simple carbohydrate, a single unit of sugar. It is found in plants and some animals, including humans. Rhamnose is also called arabinose.


Xylose is another simple carbohydrate. It’s made up of two molecules of glucose joined together and therefore contains more calories than rhamnose. Xylose is found in seaweed and mushrooms.

B. Disaccharides


Cellobiose is a simple carbohydrate made from cellulose, the main component of plant cell walls. Cellobiose is a disaccharide composed of two glucose molecules linked together.


Isomaltose is another name for hydrolysis-resistant maltose. Hydrolysis-resistant maltose is a disaccharide of two glucose molecules linked together through an alpha-1,6 bond.


Lactose is a simple carbohydrate found in milk and other dairy products. It consists of one galactose molecule linked to one glucose molecule via an alpha-1,4 bond.


Maltose is a disaccharide formed when two glucose molecules are joined together. It is most commonly used to make beer and whiskey, though it can also be found in some fruits and vegetables. Maltose is an important source of energy for plants and other organisms.

It can be broken down into glucose by enzymes called maltases or maltase-glucoamylase. These enzymes are found in human saliva and help digest maltose when we eat foods containing it.


Rutinose is another disaccharide that contains two rhamnose molecules bonded together. This sugar occurs naturally in plants such as buckwheat and is used to make medicine for treating various kinds of inflammation.


Rutinulose is another kind of disaccharide with two glucuronic acid molecules joined together. It is found naturally in the bark of some trees, such as pine trees, though it can also be produced artificially from sucrose (table sugar).


Sucrose is a simple carbohydrate in many foods, such as table sugar. It comprises two glucose molecules joined together by a glycosidic bond. This process is called glycosylation.


Trehalose is another simple carbohydrate found in certain plants and animals. Trehalose also contains two glucose molecules joined together by a glycosidic bond.

Complex Carbohydrates

Complex Carbohydrates

A. Oligosaccharide carbohydrates


Dextrin is a complex carbohydrate that can be produced from any starch. It is often used to add texture and viscosity to foods. Dextrins can be produced from corn, rice, wheat, and potato starch.

Fructooligosaccharides (FOS)

Fructooligosaccharides (FOS) are chains of fructose molecules linked together by beta bonds. Fructooligosaccharides are found in many fruits and vegetables.

Galactooligosaccharides (GOS)

Galactooligosaccharides (GOS) are chains of galactose molecules linked together by beta bonds. Galactooligosaccharides are found in legumes, peas, and soybeans.


One such type is gentianose, a complex carbohydrate found in the roots of plants such as gentian and wild ginger. It has a sweet flavor, but it also has an earthy taste and smells that can be off-putting to some people.

Isomaltooligosaccharide (IMO)

Another type of carbohydrate is isomaltooligosaccharide (IMO), a type of sugar that occurs naturally in honey. It can also be produced synthetically and added to foods like ice cream and baked goods. IMO has a distinctly sweet flavor with a hint of caramel in it.


Maltotriose is another carbohydrate that occurs naturally in barley and other grains. It has a slightly sweet taste and is often used in baking or brewing beer because it contributes to flavor and texture.

Mannan oligosaccharides (MOS)

These are complex carbohydrates that occur naturally in many foods, including soybeans and wheat bran. They can also be found as supplements in some foods and nutritional products.


This type of complex carb is found in beans and lentils. It is broken down by enzymes in the gut, making it easier to digest than other carbohydrates.


This type of complex carb is found in fruits like pears and persimmons. It’s also used to treat diabetes mellitus (DM).

B. Polysaccharide Carbohydrates

Polysaccharide Carbohydrates

Amylopectin is a polymer of glucose that’s used in the starch component of many plants. It’s also known as an alpha-1,4-glucan and contains many branch points that can be broken off and used as an energy source. In some plants, amylopectin is more prevalent than amylose.


Amylose is a linear polymer of glucose molecules that has no branch points. It’s found in cereal grains and legumes and can be broken down into maltose.


Arabinoxylan is a type of polysaccharide that’s found in plant cell walls. It is used as a food additive and dietary fiber. It’s also used to make paper and other industrial products, including paperboard.


Carageenan is a complex carbohydrate found in red algae and seaweeds. It’s a thickener in foods like ice cream, yogurt, chocolate milk, and processed cheese spreads. Carrageenan is also used to make toothpaste, cough syrups, and even beer!


Beta-Glucans are a type of complex carbohydrate found in grains like barley and oats. They’re often added to cereal products because they can help lower cholesterol levels by binding cholesterol receptors on cells called macrophages that would otherwise latch onto LDL (bad) cholesterol particles and remove them from circulation. They also seem to improve blood sugar control because they reduce the intestinal absorption of glucose.


Cellulose is a type of complex carbohydrate that’s found in plants. It’s made up of glucose molecules linked together in long chains, giving plants their structure.


Chitin is another type of complex carbohydrate that occurs in the shells of insects and crustaceans. It comprises N-acetylglucosamine units, which are sugar molecules bound together by acetyl groups.


Fructans are another type of complex carbohydrate found in many foods, including onions, garlic, and wheat. They’re made up of fructose molecules linked together, and humans can digest them—but only partially so. Fructans also include inulin as an ingredient, providing dietary fiber for our bodies to use in digestion.


A complex carbohydrate in humans and animals, glycogen is a glucose polymer. Glycogen is stored in the liver and muscles for energy.


Hemicellulose is a type of polysaccharide made up of sugar molecules bonded together. It’s found in plants as an important structural component.


Inulin is a soluble fiber found in foods like artichokes and bananas. It has been shown to help with digestive health and weight management.


Sugar alcohol is found in the sap of the African tree; nigerose is a complex carbohydrate that can be used as an alternative to sugar. It is often used in candy and toothpaste because of its ability to clean your teeth and leave a pleasant taste.


Pectin is found in many fruits, like apples and citrus fruits. It helps keep them firm while growing and can be used as a thickener in food when cooked with other ingredients.


Psyllium is a plant fiber that can thicken liquids and help keep your digestive system healthy by absorbing water inside the body. It’s often found in fiber supplements or medications for treating irritable bowel syndrome (IBS).

Xanthan gum

Xanthan gum is another plant fiber that works similarly to psyllium by absorbing water within the body and thickening liquids as well as foods like salad dressings or sauces.


There are many examples of carbohydrates available in nature. Unfortunately, having too many carbohydrates in your diet is not good for your health because carbohydrates, such as sugar and starch, can cause inflammation in the body. But eating the right amount of carbohydrates is important with all the vitamins you need to keep fit and healthy.
