The main manufacturer of own cholesterol is our liver. It produces up to 50% of this substance. 15% are produced by the intestine and 35% is produced by the largest human body - the skin. All this independently produced cholesterol is 80% concentrated in tissues. The remaining 20% \u200b\u200bfall into the body with food. His molecules that fell from food in the stomach are absorbed into the intestinal walls, from where they get into the blood, where they become part of lipoproteins.

In medicine, compounds containing cholesterol (lipoproteins) are divided into three main types:

2. High density lipoproteins (HDL). Its purpose to transfer cholesterol from cells to the liver, where it is split and excreted from the body.
