What is cholesterol?
Last updated: Thursday, October 11, 2007
This fatty substance is present in the bloodstream and in all your tissues and cells. It's necessary for human life and is made in the body by the liver. We also get it from the foods we eat.

People often think that cholesterol is the root cause of all cardiovascular disease. This is partly true, but such a view is overly simplistic. One needs to understand the role of other fats in the body as well.

Cholesterol is one of a large and important class of biological molecules called lipids, scientific jargon for fats.

One important function of lipids is to form part of the cell wall and the compartments within the cell – much as we have walls in our houses. In this way the body can set up special entry and exit ports (doors) to control the movement of substances into and within cells.

It also plays an essential role in other bodily functions, such as digestion, the manufacturing of hormones and protection of the nerve endings.
