Cholesterol: A monohydric alcohol; a sterol which is widely distributed in animal tissues. It occurs in egg yolks, various oils, fats, nerve tissue, spinal cord, brain, kidney, and adrenal cells. Cholesterol can be synthesized in the liver and is a constituent of bile. It serves as a precursor for various steroid hormones such as sex hormones, adrenal hormones, and corticosteroids. In many individuals an elevated level of cholesterol in the blood is considered to constitute an increased risk for coronary heart disease (CHD), especially elevated levels of low-density lipoprotein cholesterol (LDL) and specifically an LDL subclass (Pattern B) of small dense LDL particles.
