What is the difference between HDL & LDL?
Cholesterol, despite its bad reputation, is a substance that occurs naturally in the body. It is the chemical building block for some essential physiological processes, including the sex hormones. High-density lipoproteins (HDL) contain what is normally known as “good cholesterol”. HDL has the important job of transporting fatty acids and cholesterol to the liver for processing and elimination. Think of HDL molecules as brooms which sweep out the free cholesterol molecules from the cells that they come into contact with. As the HDL molecule encounters more cholesterol, it gets larger because it binds free cholesterol to itself.
