Which Is A Main Function Of Lipids | 6 Important Points

What Are Lipids and Their Main Function?

Lipids are a type of lipid that serves as the building blocks for our cell membranes. These little fat molecules enable the cell to store energy and prevent harmful substances from entering our cells. When it comes to making lipids, the body needs cholesterol and fatty acids. These two molecules are responsible for making the majority of the lipids that make up our bodies.

1. What are Lipids?

Lipids are essential for the body. Lipids are made up of fats that are present in the body. There are two types of lipids, saturated and unsaturated. Lipids have many benefits; the most critical use is improving your skin’s appearance. The most common lipids are oils, but there are other types of lipids as well.

What are Oils?
Oils are the most critical lipid found in the body. Fatty acids and glycerol form it. They are the primary source of fat that is present in the body. They are the primary energy source and are also used to make other lipids.

What are Unsaturated Fats?
Unsaturated fats comprise two carbon atoms with hydrogen and one carbon atom. They are also known as monounsaturated. These types of lipids are found in the body and are also used to make other types of lipids.

What are Saturated Fats?
Saturated fats are made up of four carbon atoms with hydrogen. They are also called polyunsaturated. There are many types of saturated fats like animal fats, coconut oil, butter, and lard.

What are Polyunsaturated Fats?
Polyunsaturated fats are made up of two carbon atoms with hydrogen. They are also called omega three and omega 6. Many polyunsaturated fats include fish oil, vegetable oil, flax seed oil, olive oil, and almonds.

Benefits of Lipids
It is widespread to get wrinkles and lose the skin’s elasticity as you grow older. But by applying lipids, you can prevent it.
If you are a teenager and your skin is not looking good, it is time to use lipids. Lipids will make your skin look healthy, shiny, and firm.
The main reason to use lipids is to reduce the appearance of wrinkles and get a youthful glow.

So, now you know what lipids are. If you have any questions regarding lipids, then you can ask us. We will guide you about the importance of lipids.

2. Main Functions of Lipids

Lipids are molecules that consist of fats, waxes, and sterols. Lipids are used in the human body for many purposes. Here, I will discuss some of the main functions of lipids and how they can be used.

Functions of lipids:
Lipids perform various functions in the human body. They are used for digestion, absorption, nerve transmission, brain development, hormone production, energy storage, and many more.

The lipids include triglycerides, phospholipids, cholesterol, and waxes. They are present in food, blood, and body tissues. They are used for the maintenance of cell membranes, transport of hormones and other vital molecules, and also for the formation of hormones.

Cholesterol is the essential lipid in the human body and is used to construct cell membranes and other vital functions. It is also used to make bile salts for the digestive system. It is found in many foods like eggs, meat, cheese, fish and other seafood, nuts, and avocados.

It is one of the numerous standard lipids, forming when the fatty acids bind together to form a single chain.

They are waxy substances that consist of fatty acids. The lipids are used to protect and lubricate the skin, hair, and nails.

Lipids are one of the essential parts of the human body. They are used for numerous functions, and their deficiency can lead to several diseases.

3. How Are Lipids Used in Lipid Therapy?

Lipids are used in Lipid Therapy for treating diseases like diabetes, cardiovascular disease, etc. Lipids are classified into five types: triglycerides, phospholipids, free fatty acids, cholesterol, and ceramides.

The triglycerides are the primary type of lipid, and they are found in animal fats and vegetable oils. They are present in the food and body fluids and are also produced by the liver.

They are also known as phospholipids and are present in the human body. They form the cell membrane and carry nutrients to the cells. They also carry oxygen to the tissues of the body.

Free Fatty Acids:
They are also called FFAs and are present in high concentrations in body fat. They are also involved in hormone production and metabolism.

They are also called sterols and are the major component of the cell membranes. They are also found in the adrenal glands and brain.

They are also known as ceramides and are involved in skin maintenance. They help to maintain the barrier function of the skin.

These are the five main types of lipids. All these lipids are used in Lipid therapy to treat different diseases.

4. Lipid-Targeted Therapies

Heart illness is the immediate reason for death in developed countries. In 2014, around 6.3 million people died due to heart disease. But lipid-targeted therapy is not only helpful in preventing heart disease but also has the power to treat it effectively.

What are Lipid-Targeted Therapies?
Lipid-targeted therapies are drugs specially designed to target specific lipids in the body. Lipids are compounds like fats, cholesterol, and triglycerides. Lipid-targeted therapies are usually used to treat diseases such as high cholesterol, low HDL, hypertriglyceridemia, and atherosclerosis.

Elevated blood cholesterol is a substantial threat factor for coronary artery disease, one of the leading causes of heart disease. According to the National Cholesterol Education Program, around 25% of men and 35% of women have blood cholesterol levels higher than recommended. High blood cholesterol raises the chance of heart attack, stroke, and other cardiovascular diseases.

Blood clots are estimated to trigger almost 75% of all heart attacks. These clots are formed when a protein called fibrin forms in the blood, and the resulting clot becomes hard and adheres to the vessel wall.


The drug Lipitor (atorvastatin) is a lipid-targeted therapy that lowers blood cholesterol levels. It is the best drug approved by the FDA to treat high cholesterol. Lipitor is available as a pill but comes in a liquid form.

What Are the Effects of Lipid-Targeted Therapies?
Lipid-targeted therapies can significantly reduce the risk of cardiovascular disease, and they can also help to lower LDL cholesterol levels. According to the US Food and Drug Administration, Lipid-targeted therapies can:

• Lower total cholesterol and LDL cholesterol.
• Decrease the size of existing plaques and help prevent new ones from forming.
• Improve blood flow to the heart and brain.

• help prevent the progression of atherosclerosis.
• Prevent strokes and heart attacks.
• Protect against heart failure.

Lipid-targeted therapies can improve the quality of life of patients with high cholesterol. They can also prevent the symptoms of heart disease, such as chest pain and shortness of breath.

Although lipid-targeted therapies can be very effective, they are not suitable for everyone. Some people cannot take Lipitor or other lipid-lowering drugs because of side effects.

Lipid-targeted therapies are not only helpful in preventing heart disease but also have the power to treat it effectively. I hope you enjoyed this position about how to use Lipid-Targeted Therapy to Prevent and Treat Heart Disease. I have also shared with you some practical ways to get rid of blackheads.Which Is A Main Function Of Lipids | 6 Important Points
