Cholesterol is a vital cell building block in humans and animals, and an integral part of the so-called cell membrane. This boundary layer separates the interior of the cell from the neighboring cells and the surrounding environment. By means of certain proteins, it ensures that various chemical messengers can enter or exit the cell. In addition, cholesterol is the precursor of various hormones and bile acids. The level of cholesterol in the blood is also associated with numerous diseases, in particular of the cardiovascular system, but also with the very rare but particularly serious so-called lysosomal storage disorders.
