Cholesterol

Cholesterol
This fatty substance is present in the bloodstream and in all your tissues and cells.

How lipids move
The process entails transport of biological compounds between tissues.

Triglycerides
A triglyceride is a molecule formed by three fatty acid chains linked to a molecule of glycerol.

Cholesterol, triglycerides - origin
There are two main sources of cholesterol and triglycerides: external and internal sources.

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

HDL and LDL
An increased level of HDL cholesterol is associated with a lower risk of coronary heart disease (CHD).

Triglycerides and heart problems
Triglycerides are usually measured as part of a standard blood lipid profile. But what do the results mean?

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