Lipoproteins are particles containing both fats and proteins. It is their job to transport cholesterol via the bloodstream and lymphatic fluid. Since cholesterol is insoluble in blood, it must be bound to lipoproteins to be transported.
There are two main types of lipoprotein and include low-density lipoproteins and high-density lipoproteins.
1. Low-density lipoproteins (LDLs) transport cholesterol from the moment it is synthesised in the liver to the body tissues and cells.
2. High-density lipoproteins (HDLs) transport any excess or unused cholesterol from the body tissues back to the liver.
Low-density lipoproteins carry about 70-80 percent of cholesterol across the body, and they are commonly blamed for causing a build-up of fatty deposits. High-density lipoproteins, on the other hand, clean up and pick up any excess or residue cholesterol, reducing the risk of cholesterol build-up and potentially improving health.« Back to Glossary Index
