Cholesterol is a soft, fat-like substance found in all your body's cells. It's a key part of a healthy body, because it's used to form cell membranes, some hormones and other needed tissues. It can be a problem if you have too much of it in your body.
Cholesterol comes from two sources.
It's made in your body, mostly in the liver. It's also found in foods from animals, such as meats, poultry, fish, seafood, and dairy products. Egg yolks have lots of cholesterol in the diet.

However, cholesterol and other fats can't dissolve in the blood, so they have to be transported to and from cells by special carriers called lipoproteins.
