Cholesterol is made in your liver and has many important functions. For example, it helps keep the walls of your cells flexible and is needed to make several hormones.
However, like anything in the body, too much cholesterol (or cholesterol in the wrong places) creates concerns.
Like fat, cholesterol does not dissolve in water. Instead, to move around the body, it depends on molecules called lipoproteins. These carry cholesterol, fat, and fat-soluble vitamins in your blood.
