Functions of Cholesterol

Cholesterol is a waxy fluidly substance that takes from two sources: your body and nutritious food. Your body, and especially your liver, produce all the cholesterol you need and secrete it through the blood stream. But cholesterol is also found in meals from animal sources, poultry, and full-fat dairy products. Your liver makes more cholesterol when you eat up a diet high in saturated and trans fats.

Function of cholesterol

An excess amount of cholesterol can form plaque between layers of artery walls, making it stiff for your heart to pump blood. Plaque can break open and result in blood clots. If a clot blocks an artery that carries blood to the brain, it causes a stroke. If it blocks the path to the heart, it causes a heart attack, which can lead you to death.

Types of Cholesterol and their Functions:

There are merely two types of cholesterol, i.e. “good” and “bad.” Too much of one type, or not sufficient of another, can lead you to risk for coronary heart disease, heart attack or blood stroke. It is significant to know the proper levels of cholesterol in your blood flow so that you and your doctor can determine the good strategy to reduce the risk.

LDL cholesterol (bad cholesterol):

LDL cholesterol also is known as “bad” cholesterol. A high LDL level can lead to an assembling of cholesterol in your arteries. (Arteries are muscular blood vessels that deliver oxygenated blood from your heart to your body).


HDL cholesterol (good cholesterol):

HDL cholesterol sometimes refers as “good” cholesterol. Due to, it carries cholesterol back to your liver by collecting to whole body parts. Your liver then helps in removing the cholesterol from your body.

Functions of Cholesterol:

Digest fatty substance through bile production:

Cholesterol is also used in the formation of bile, a greenish fluid that is secreted by the liver and stored in the gallbladder. The body requires bile to break up foods that compose fatty substance. Bile performs as an emulsifier, it splits down sizeable globules of fat into smaller molecules so they can mix smoothly with the enzymes that digest fat. Once the fat is completely digested, bile helps the body to absorb it and acts a supportive end. The production of bile in the intestines is needed before cholesterol can be absorbed from nutritious foods. The body also require bile in order to absorb vitamins A, D, E, and K, the fat-soluble vitamins, derived from healthy nourishment.

Building blocks as supportive unit or component:

As its a structural supportive component of cells and along with polar lipids makes it the structural part of every cell in our body. Cholesterol is there to actually shield a protective barrier. When the responsible amount of cholesterol increases or decreases, the cells may affected. This minute change can affect our capability to metabolise and provide energy, which can ultimately affect other parts of our body and helps in function such as food intake and digestion.

Enhancing up Immune system:

Cholesterol is crucial for our immune system to function effectively. Our immune cells base on cholesterol to fight against infections and repair themselves after the fight. Furthermore, LDL-cholesterol, also called bad cholesterol, directly binds and immobilizes dangerous bacterial toxins, halting them from doing any damage in the body. People with low-level cholesterol are prone to different infections, suffer from them longer and are more probable to die from an infection.

When the body has some healing jobs to do, it produces some cholesterol and supplies it to the site of the damage that is why regarded it as a chief healing agent. When we have a brutal infection, LDL-cholesterol goes up to against with the bacterial or viral disease.

Immune defense

Prominent Symptoms:

Having high-level cholesterol, while a danger factor for rest conditions, does not itself present any symptoms. Unlikely, routinely screened via regular blood testing, high cholesterol levels will go unnoticed and could produce poisonous a silent threat of heart attack or stroke.

Making healthy eating decisions and boosting the time of exercise are important first steps in maintaining your cholesterol. For some people, cholesterol-lowering medication may also be required to lesser the danger for heart attack and stroke. So, make sure you will adopt all the above instructions.

  • Building blocks as supportive unit or component.
