Cholesterol can:
  • Cause your arteries to narrow (atherosclerosis).
  • Increase your risk of heart disease.
  • Cause a heart attack from a clot in a coronary artery.
  • Keep your heart from getting enough blood which leads to chest pain (angina).
  • Cause a stroke when a clot keeps oxygen from the brain, or other cardiovascular conditions.

There are three kinds of cholesterol:
  • LDL or low density lipoprotein: If there is an excess of this type of lipoprotein, then your risk for arterial disease increases.
  • HDL or high density lipoprotein: This is called the good cholesterol because it prevents arterial disease by taking cholesterol from the cells and putting them in the liver where they are broken down or flushed away.
  • Triglycerides: Along with cholesterol, these make up the plasma lipids. Any calories you do not use are changed into triglycerides and stored as fat for use later.

Most doctors want your cholesterol to be under 200 mg/dl. Borderline is considered between 200 and 230 mg/dl, with high being 240 mg/dl and higher.

An example of cholesterol is a waxy substance that is found in the cells of all animals and human beings.

A white crystalline substance, C27 H45 OH, that is found in animal tissues and various foods and is important as a constituent of cell membranes and a precursor to steroid hormones. Cholesterol is normally synthesized by the liver and is transported through the bloodstream by different types of lipoproteins, two of which (HDL and LDL) are routinely measured in blood tests.

A sterol found widely in animal and plant tissues. It is a main component of blood plasma and cell membranes, and it is an important precursor of many steroid hormones (such as the estrogens, testosterone, and cortisol), vitamin D2 , and bile acids. In vertebrates, cholesterol is manufactured by the liver or absorbed from food in the intestine. Higher than normal amounts of cholesterol in the blood are associated with higher risk for developing coronary artery disease and atherosclerosis. Chemical formula: C27H46O.

(biochemistry) A sterol lipid synthesized by the liver and transported in the bloodstream to the membranes of all animal cells; it plays a central role in many biochemical processes and, as a lipoprotein that coats the walls of blood vessels, is associated with cardiovascular disease.
