There are four types of lipoproteins:

- Chylomicrons, which transport lipids from the intestine in different organs.

- LDL (Low Density Lipoproteins) or low density lipoproteins that carry the bulk of cholesterol. LDL cholesterol is often called “bad” cholesterol because it is one of those responsible for the formation of atherosclerotic plaques in arteries.

- VLDL (Very Low Density Lipoproteins) lipoprotein or very low density, also rich in triglycerides.

- HDL (High Density Lipoproteins) or high density lipoproteins that transport mainly phospholipids and some cholesterol. HDL cholesterol is considered “good” cholesterol because it protects the arteries against atherosclerosis.
Triglycerides

Triglycerides are fats in the blood. Their blood levels may be higher in a diet that contains too much sugar, alcohol, or obesity. Triglyceride must be regularly performed in cases of oral contraceptive use.
Cholesterol

When measuring the “cholesterol”, it actually measures the rate of lipoprotein used to transport cholesterol and other fats in the blood.

LDL cholesterol is below normal at 1.60 g / l and should be less than 1.30 g / l if the presence of cardiac risk factors.

The balance of blood lipids should be performed after an overnight fast.
Apolipoproteins

These are proteins on the surface of lipoproteins, whose rate is significantly different levels of blood fats. The apolipoprotein A1 are located in the particles that contain cholesterol HDL. Apolipoprotein B is in particles that contain cholesterol, LDL and VLDL and chylomicrons.
