Cholesterol

Natural fatty substance found in the human body. Cholesterol is an important building material that plays an important role in the stabilization of Zellmembran/en and in nerve cells. It is assumed that too high values in the blood promote arteriosclerosis.

Cholesterol is a lipid that occurs freely in the entire human organism and in the form of cholesterol esters. It represents the precursor of bile acids and steroid hormones, is an essential component of cell membrane and myelin sheaths; it is particularly enriched in adrenal gland (3%), brain (10% of dry matter; only free cholesterol), skin (24% of the skin fat), spleen, ovaries, serum and erythrocytes.

It is predominantly taken from food (exogenous cholesterol), which is obtained as required from the body's own depots, especially from the liver) or is provided by biosynthesis, also mainly in the liver (endogenous cholesterol).
