Cholesterol and Health
Here's what you need to know
What are LDL and HDL?
Low-density lipoprotein (LDL) is one of the five major groups of lipoprotein. LDL is a microscopic blob that's made up of an outer rim of lipoprotein that surrounds a cholesterol center.
High-density lipoproteins (HDL) are another one of the five major groups of lipoproteins. It travels through the bloodstream. As it does, it removes harmful LDL cholesterol from where it doesn't belong. High HDL levels reduce the risk of heart disease, but low levels increase the risk.
How do they differ structurally and functionally?
Functionally, LDL brings cholesterol to cells throughout your body and may cause it to buildup within your arteries, which can lead to an increased risk of heart disease, among other things. HDL carries cholesterol away from your heart and other organs and deliver it back to the liver, so there is no damage being done.
