Cholesterol occurs as white or faintly yellow, almost odorless, pearly leaflets, needles, powder, or granules. On prolonged exposure to light and air, cholesterol acquires a yellow to tan color.
cholesterol: A sterol occurringwidely in animal tissues and also insome higher plants and algae. It canexist as a free sterol or esterified witha long-chain fatty acid. Cholesterol isabsorbed through the intestine ormanufactured in the liver. It servesprincipally as a constituent of bloodplasma lipoproteins and of thelipid–protein complexes that formcell membranes. It is also importantas a precursor of various steroids, especiallythe bile acids, sex hormones,and adrenocorticoid hormones. Thederivative 7-dehydrocholesterol isconverted to vitamin D3 by the actionof sunlight on skin. Increased levelsof dietary and blood cholesterol havebeen associated with atherosclerosis,a condition in which lipids accumulateon the inner walls of arteries andeventually obstruct blood flow.
Cholesterol is a soft waxy substance that is a steroidal alcohol or sterol. It is the most abundant steroid in the human body and is a component of every cell. Cholesterol is essential to life and most animals and many plants contain Cholesterol. Cholesterol biosynthesis occurs primarily in the liver, but it may be produced in other organs. A number of other substances are synthesized from cholesterol including vitamin D, steroid hormones (including the sex hormones), and bile salts. Cholesterol resides mainly in cell membranes.Humans produce about 1 gram of cholesterol daily in the liver. Dietary cholesterol is consumed through food. High cholesterol foods are associated with saturated fats and trans-fatty acids (commonly called trans fats). Dietary cholesterol comes from animal products (plants contain minute amounts of cholesterol) such as meats and dairy products.
The CAS number of Cholesterol is 57-88-5.
