Lipid Properties, Types And Functions

The action of lipids is important for the body. They are not only energy stores but also involved in the transport of certain nutrients. How are lipids classified? Let’s see!
Properties, types and functions of lipids

The action of lipids is important because they affect overall health. Not only are they relevant to the body’s energy storage, but they are also involved in other important processes,  such as the transport of nutrients and the regulation of body temperature.

Lipids are multidimensional and come from a number of different sources. They are known for their role in caring for living beings. This is because lipids are important in linking vitamins as well as maintaining optimal metabolic function.

So what exactly are lipids? What is their role? You may have heard of them when talking about health and nutrition, but would you like to know more about them? Keep reading.

The role of lipids

Lipids are a group of biological molecules that are involved in the body’s essential processes. They are part of the cell membrane and form the basis for hormone production. They are primarily responsible for storing energy.

They consist of carbon and hydrogen and contain less sulfur, nitrogen and phosphorus. However, the main property of lipids is their insolubility in water and the maintenance of the body’s energy supply.

The word “lipid” usually refers to “fat,” but not all lipids are fats. All fats, in turn, are lipids. However, there are several types of lipids and they are classified according to their physical properties and functions.

The importance of lipids in the body.
The main function of lipids is to act as the body’s energy store. However, they are also involved in, among other things, the production of hormones and the synthesis of vitamins.

Lipid types

As noted in an article in the scientific journal Biochimica et Biophysica , lipids combine several different components with significant biological functions. It is therefore important to understand their classification when talking about such substances. What types of lipids exist?


These lipids consist of chains containing fatty acids, phosphate and glycerol. They form a hydrophobic structure, which means that they repel water. Their main function is the formation of cell membranes.

They also perform other functions, such as digestion of other fats in the small intestine. The body is able to create all the phospholipids it needs on its own.


This substance is an important molecule in the body. Contrary to what many people think, cholesterol is not always a bad thing and it is part of the cell membrane. It is also a sign of various substances such as vitamins and steroid-like hormones. 

Thus, a certain amount of cholesterol is important for the proper functioning of the body. However, excessive amounts can lead to the accumulation of cholesterol in the blood vessels. This can be problematic because it carries a higher risk of having a heart attack or ischemic illness when the blood vessels become blocked.


These fats also have sugar molecules in their structure. Their main function is related to the immune system. They live outside the cell membrane and act as its signal.


These molecules are made up of fat and alcohol. They are molecules that are converted into excess energy or sugar in the body. So they create their own energy store. 

As with cholesterol, excessive triglycerides also tend to accumulate in blood vessels and elsewhere in the body. For this reason, high levels of triglycerides can cause health problems.

Lipid storage in the body.
Triglycerides play an important role in storing energy in the body. However, excessive amounts can be harmful to health.


These molecules are made up of cholesterol and hormones. Testosterone and estrogen are examples of such molecules. They need cholesterol to be able to be synthesized with the body. They perform functions that regulate and activate the body.

What is the role of lipids in the body?

Lipids have many important functions in the body depending on their type. According to an article in Molecular Biology of Cell , the tasks are structural or communicative. We describe below their main tasks.

The main function of lipids is to store energy

The main function of this substance is energy storage. One gram of fat can bring nine kilocalories into the body. When a person eats too much sugar, it accumulates in the form of fat stores. The body uses them when a person is deficient in other energy sources such as carbohydrates.

Formation of structures

Some lipids form important structures in the body. Cell membranes are the most significant example of these. They consist of certain types of lipids, which in turn are important for cell protection and shape retention.

The role of lipids is to promote cell-cell interaction

Cells communicate with each other through various substances that act as signals. Examples of such substances are vitamins, hormones and glycolipids. Their job is to regulate a number of secretions and reactions in the body. 

Intercellular communication would not be possible without certain lipid types.

The transport of other substances is also one of the most important functions of lipids

Some lipids carry other substances (such as nutrients) through the body. This function is generally performed in combination with bile acid and lipoprotein.

Thermal regulation

Fat stores accumulate under the skin and around the organs, protecting the body from the cold. Fat traps heat inside and thus keeps the body warm.


The functions and types of lipids are varied as well as complex, although in general  these organic constituents are essential for life. They are also to some extent crucial to the proper functioning of the body. However, some of them are harmful if there are too many of them.

As you can see, it’s important to try to shape and maintain a healthy lifestyle, especially when it comes to food. It is also recommended to have regular health check-ups. If the lipid level is abnormal, medication should be started to treat it.
