For thousands of functions in human life: what is the function of lipids?


You probably remember studying the lipids and their role within the human body at school, but if you do not remember what these organic molecules are and what they are for within our body, we will tell you.

Indeed, these molecules that are considered within the metabolism, develop some essential actions for human life, such as storage that allows energy to be obtained, starting from elements such as fats and, among them, famous triglycerides and cholesterol.

But although the main task carried out by lipids within the body has to do with this storage, that is not the only obligation they have and that is why, in the following lines, we are going to analyze some other activities that also affect them, and that explain its undeniable importance.

4 functions of lipids in the body

Regulate body temperature

By storing the fats that we consume, lipids are not only capable of obtaining energy, but are also essential to withstand low temperatures, and it is precisely for this reason that, when winter arrives, our body asks us to add calories to the diet .

Nerve impulse transmitter

Generally more associated with the digestive system, lipids also have their work as part of the nervous system. The lipid membraneAs it is known, it has myelin, which allows impulses or signals to travel more quickly through the axons of the nerves.

Signal emitters

Testosterone and estrogens, two of the most popular steroid hormones, are nothing more than lipids that emit signals when they come into contact with proteins in the blood.

They even facilitate the genetic changes that the body requires, communicating the cell membranes with receptors, and thus paving the way for modifications in this area of ​​biology.

Energy storage

In the event that we are introducing a greater amount of fat to our body than we need, the surplus will begin to accumulate as adipose tissues, becoming an eventual source of extra energy in the face of cold or fasting.

From an aesthetic point of view, this justifies those “rolls” that we get when we eat too much.


In summary, lipids are constitutive and essential for the human body, and although they are often cited as synonymous with fats, not all fats are healthy for the body, which requires a balanced diet that incorporates each nutrient in just the right amount.
