Major Difference Between LDL and VLDL, And Its Effect

Any member of a group of substances containing both lipid (fat) and protein. They occur in both soluble complexes—as in egg yolk and mammalian blood plasma—and insoluble ones, as in cell membranes. Lipoproteins in blood plasma have been intensively studied because they are the mode of transport for cholesterol through the bloodstream and lymphatic fluid.

Various types of lipoproteins are high-density lipoprotein, low-density lipoprotein and very-low-density lipoprotein, or, respectively, HDL, LDL and VLDL.

Out of this, High-density lipoprotein is the good cholesterol that benefits your heart. This cholesterol works by transporting damaging low-density lipoprotein and very-low-density lipoprotein to your liver, where they are broken down, allowing your body to eliminate them.

While VLDL and LDL are both considered types of “bad” cholesterol, your body needs both cholesterol and triglycerides to function, having too much of them can cause them to build up in your arteries. This can increase your risk for heart disease and stroke.

What Is The Difference Between LDL And VLDL?

Very low density lipoprotein (VLDL)
• VLDL (very-low-density lipoprotein) is a type of lipoprotein found in circulation. It is created in the liver and carries triglycerides throughout the body.
(Density- 0.95 – 1.006g/ml)
• Generally, VLDL contains 10% of cholesterol, 70% of triglycerides, 10% of proteins and 10% of other fats.
•The cells in your body use triglycerides that are carried by VLDL for energy.
• Eating more sugars or carbohydrates than your body can burn will result in a high amount of VLDL and an excessive amount of triglycerides in the blood.
However, fat cells store the excess triglycerides for future use for energy.
• Healthy range of very-low-density lipoprotein falls between 2 and 30 milligrams per deciliter.
•High levels of triglycerides are linked to the buildup of hard deposits in your arteries. These deposits are called plaques. Plaque buildup increases your risk of heart disease and stroke.

Low density lipoprotein
•LDL (low-density cholesterol) is another type of lipoproteins in the blood. Usually, VLDL is converted into LDL by the action of enzymes in the blood. The rest of VLDL is transformed into LDL by enzymes in the blood. LDL has fewer triglycerides and a higher percentage of cholesterol than VLDL.
(Density- 1.019 – 1.063g/ml)
•LDL is largely made up of 25% cholesterol, 10% triglycerides, 25% proteins, and 15% other fats.
•LDL transports fat molecules, including fat molecules (phospholipids, triglycerides, cholesterol, etc.) around the body. Too much cholesterol in your body leads to high LDL levels.
•Low-density lipoprotein needs to stay below 100 milligrams per deciliter.
•Low-density lipoprotein is very damaging to your cardiovascular system. High LDL levels are also associated with the buildup of plaque in your arteries.
These deposits can eventually lead to atherosclerosis. Atherosclerosis occurs when deposits of plaque have hardened and narrowed the artery. This increases your risk of having a heart attack and stroke.
