High cholesterol can be attained by anyone irrespective of gender, physical appearance, and age. The bad reputation of cholesterol is caused by its waxy nature which not wanted by people as it can affect the working of your body cells by forming membranes in them and becomes harmful for everyone.

Formations of HDL and LDL

In fact, cholesterol molecules known as lipids are a kind of insoluble substance consisting of oils, fats, and waxes in your body. Being insoluble in water content and other fluids in your body, cholesterol uses them as a ride and travels throughout your body with blood. During its journey through your body cholesterol combines with protein to form lipoproteins by coating cholesterol molecules.

The molecules of cholesterol highly coated with proteins popularly known as HDL cholesterol or good cholesterols, rush through your body to ultimately reach your liver to be converted into bile acids. The low quantity of HDL in your blood causes very fewer health risks.

When the protein coating on cholesterol molecules is lesser than HDL then they travel unevenly through your blood and are received by various receptors in your veins that attract these lipoproteins while passing through them which increases the risk for hypertension, stroke and heart diseases.

This kind of lipoproteins is known as LDL cholesterols or bad cholesterols. They leave a bit of them over there while passing through your arteries. HDL sees a stack of LDL in its way then the later one strikes into former one creating plaques and platelets in the arteries.

Besides good and bad characters of HDL and LDL cholesterols, they are needed essentially for many necessary functions of your body. Cholesterol is important for the stability of the cellular membranes. Cholesterols converted into bile acids are also necessarily needed for improving the digestive system and producing vitamin D and sex hormones.

Role of food information of HDL and LDL

Both types of cholesterols are formed by your cells on the basis of the food you eat which may include cholesterol-rich food, cholesterol-free foods, animal-based foods, and various other types of foods. The building blocks of cholesterols are made by breaking up the elements of the food you eat into fatty acids.

The enzymes existing in your small intestines and stomach reacts with the fats proteins and carbohydrates you eat to convert them into various types of smaller molecules like fatty acids etc. which in turn combine with other elements in your body to form chylomicrons which travel with your blood into your body. Some of these chylomicrons are used by your liver to produce HDL and LDL and some of them provide energy to your body cells.

Role of the liver in the formation of HDL and LDL

Though cholesterols are produced by various parts of your body your liver is the most efficient of them all to use chylomicrons received from your digested food to for cholesterols of both kinds, HDL and LDL.

Some of the enzymes contained in your lever help in the production of cholesterol and some other help in producing the proteins and combining them with the cholesterol molecules to form LDL and HDL according to the individual nature of the molecules. The HDL and LDL molecules once produced are released by the liver into your bloodstream to travel into various other parts of your body.

Effects of formation of HDL and LDL

Both the types of cholesterol, LDL, and HDL, are not harmful to your health unless the level of cholesterol on LDL molecules does not increase excessively. LDL with very high cholesterol levels usually releases its cholesterols to the arteries to deposit them in the form of plaques which in turn narrows the walls of the arteries by clotting on them which increases the risk of strokes and heart diseases. HDL, on the other hand, helps in removing excessive cholesterols traveling through your blood vessels and carrying them back to your liver.

Thus, HDL and LDL play an important role in your body if kept under control.
