Cholesterol and blood lipids

Learn more about cholesterol and blood lipids including fatty acids, tryglycerides, phospholipids and lipoproteins that transport biological compounds between tissues.

What are blood lipids?

Apart from cholesterol, there are several other biologically important lipids (fats) in the body.

Measure lipoproteins

The lipoproteins (LPs) have historically been the focus of research into the causes of atherosclerosis and coronary artery disease.


A triglyceride is a molecule formed by three fatty acid chains linked to a molecule of glycerol. Triglycerides are nature’s best way of storing energy.

How lipids move

The process entails transport of biological compounds between tissues.


An increased level of HDL cholesterol is associated with a lower risk of coronary heart disease (CHD). But extremely high or low levels may not follow the rule.
