Cholesterol is a lipid, a type of fat that is found in the bloodstream and the cells of the body, is an important component of a healthy organism; cholesterol is used in our metabolism to produce cell membranes and some hormones, as well as participating in other vital processes in the body.
Refers to two types of cholesterol, the good and the bad, but cholesterol is actually one single and this classification refers to the lipoprotein that transports it.
LDL or low density lipoprotein is associated with the “bad cholesterol” because it makes the transport of cholesterol into artery walls and thence to the tissues, and HDL or high-density lipoprotein that transports cholesterol from tissues to the liver for metabolism, is associated with “good cholesterol”.
