Classified as a sterol and is an important fat-soluble compound in animal cells (therefore, animal fats), but only found in trace amounts in plants (therefore, vegetable oils).

(n) an animal sterol that is normally synthesized by the liver; the most abundant steroid in animal tissues

A waxy, fat-like substance produced by the liver and found in all food from animal sources; an essential component of body cells and a precursor of bile acids and some hormones.

The name for a group of blood fats. It includes LDL, or low-density lipoprotein, which is ‘bad’ cholesterol; HDL, or high-density lipoprotein, which is ‘good’ cholesterol; and triglycerides (TG). A hi [..]

(ko-LES-te-rol) Cholesterol is a fat-like substance that is made by your body and found naturally in animal foods such as dairy products, eggs, meat, poultry, and seafood. Foods high in cholesterol include dairy fats, egg yolks, and organ meats such as liver. Cholesterol is needed to carry out functions such as hormone and vitamin production. It is [..]

A fatty substance, one of several different types of fat found in the body. If blood vessels are damaged, cholesterol can be deposited, eventually causing narrowing.

An amphipathic lipid containing the four-ring steroid structure with a hydroxyl group on one ring; a major component of many eukaryotic membranes and precursor of steroid hormones. (Figure 5-29)

 a waxy substance that comes from two sources: your body and food. Your body, and especially your liver, makes all the cholesterol you need and circulates it through the blood. But cholesterol is also found in foods from animal sources, such as meat, poultry and full-fat dairy products. Your liver produces more cholesterol when you eat a diet high [..]
