This substance is involved in building cell membranes, provides protection of the inner parts of cells against the effects of external factors. It ensures the integrity of cell structure. The creation of the lipid layer helps to strength the protective properties of the cell membrane.

Ensuring the normal functioning of cells allows ensuring good health for the whole organism. In the process of life, cells undergoing shape changes and processes of existence.

- Thus, cholesterol is an important Sterol in the group of the sterols in the animal organism. Most cholesterol comes from the outside. But the body is able to produce cholesterol through the specialized liver cells. In a healthy organism, the liver cells to fully provide the body with the necessary amount of cholesterol.
- The body is able to maintain their health independently. Researchers examined the consumption of cholesterol in animal and vegetable cells. Some types of bacteria are not need of the presence of cholesterol. Other types of bacteria use cholesterol for growth. The presence of cholesterol provides organism health.
