What it is and how it works
- LDL is a type of lipoprotein. A lipoprotein is a combination of protein and lipid.
- LDL transports cholesterol to the cells of the body.
- Like all lipoproteins, LDL contains an inner core of cholesterol and an outer shell made of phospolipids and proteins.
- LDL has low density because the molecules have more cholesterol than protein. In comparison to HDL molecules LDL molecules are bigger.
- HDL is another lipoprotein in the body.
- HDL transports cholesterol to the liver from excess in the blood stream.
- HDL has more protein than cholesterol and fat, so it has a higher density. HDL molecules are smaller than LDL molecules.
Heart Disease Risks
- Too much LDL in the blood can cause cholesterol to build up in the arteries. -Plaque is what blocks the arteries. - This can lead to hardening of the arteries and heart attack or stroke.
How is LDL And HDL Monitored
- LDL and HDL can be monitored through lipidprotein analysis.
- Lipidprotein analysis also monitors: - Overall cholesterol - Triglycerides
