3beta-hydroxy-5-cholestene

콜레스테롤 C화학적 특성, 용도, 생산

개요

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 this compound. 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.

화학적 성질

White to faintly yellow cryst. powder

화학적 성질

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.

역사

Cholesterol was discovered in 1769 by Poulletier dela Salle (1719–1787), who isolated the compound from bile and gallstones. It was rediscovered by Michel Eugène Chevreul (1786–1889) in 1815 and named cholesterine. The name comes from the Greek words khole meaning bile and steros meaning solid or stiff . The “ine” ending was later changed to “ol” to designate it as an alcohol.

용도

Cholesterol is commonly associated with cardiovascular disease and its routine measurement is used to measure its potential health risk. High blood serum cholesterol levels are often correlated with excessive plaque deposits in the arteries, a condition known as atherosclerosis or hardening of the arteries. Although high total blood cholesterol levels are associated with heart disease, it is important to distinguish between types of cholesterol when interpreting cholesterol levels. Cholesterol has been labeled as good and bad depending on its physiological role. Forms of cholesterol depend on the lipoproteins that are associated with it. Lowdensity lipoprotein cholesterol (LDL cholesterol) is often referred to as bad cholesterol and high-density lipoprotein (HDL) is identified as good cholesterol. An understanding of the difference between LDL and HDL cholesterol requires an understanding of substances associated with cholesterol in the body. Cholesterol is a lipid so it has very low solubility in water and blood. For the cholesterol synthesized in the liver to be delivered by the bloodstream to the rest of the body, the liver manufactures lipoproteins that can be viewed as carriers for cholesterol (and triglycerides).

용도

cholesterol is a moisturizer and emollient that acts as a powerful emulsifier in water-in-oil systems. Cholesterol is a fat-like substance found in plant and animal cells. It is also present in the secretion of the sebaceous glands and, therefore, is a component of the fat on the skin’s surface. It is considered a noncomedogenic raw material. It may sometimes be obtained from sheep’s wool wax.

용도

analeptic, antibacterial

용도

Cholesterol is a major component of all biological membranes; ~25% of total brain lipid is Cholesterol. Cholesterol is the principal sterol of the higher animals. Cholesterol was found in all body tis sues, especial in the brain, spinal cord, and in animal fats or oils. Cholesterol is the main constituent of gallstones.

용도

Cholesterol be used as pharmaceutical intermediates and be used as synthetic materials of liquid crystal polymers.

정의

ChEBI: A cholestanoid consisting of cholestane having a double bond at the 5,6-position as well as a 3beta-hydroxy group.

정의

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.

생산 방법

The commercial material is normally obtained from the spinal cord of cattle by extraction with petroleum ethers, but it may also be obtained from wool fat. Purification is normally accomplished by repeated bromination. Cholesterol may also be produced by entirely synthetic means.
Cholesterol produced from animal organs will always contain cholestanol and other saturated sterols.

위험도

Questionable carcinogen.

Pharmaceutical Applications

Cholesterol is used in cosmetics and topical pharmaceutical formulations at concentrations of 0.3–5.0% w/w as an emulsifying agent. It imparts water-absorbing power to an ointment and has emollient activity.
Cholesterol also has a physiological role. It is the major sterol of the higher animals, and it is found in all body tissues, especially in the brain and spinal cord. It is also the main constituent of gallstones.

Safety Profile

Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Mutation data reported. Used in pharmaceutical and dermal preparations as an emulsifying agent. When heated to decomposition it emits acrid smoke and irritating fumes.

Safety

Cholesterol is generally regarded as an essentially nontoxic and nonirritant material at the levels employed as an excipient. It has, however, exhibited experimental teratogenic and reproductive effects, and mutation data have been reported.
Cholesterol is often derived from animal sources and this must be done in accordance with the regulations for human consumption. The risk of bovine spongiform encephalopathy (BSE) contamination has caused some concern over the use of animalderived cholesterol in pharmaceutical products. However, synthetic methods of cholesterol manufacture have been developed.

저장

Cholesterol is stable and should be stored in a well-closed container, protected from light.

Purification Methods

Crystallise cholesterol from ethyl acetate, EtOH or isopropyl ether/MeOH. [Hiromitsu & Kevan J Am Chem Soc 109 4501 1987.] For extensive details of purification through the dibromide, see Fieser [J Am Chem Soc 75 5421 1953] and Schwenk and Werthessen [Arch Biochem Biophys 40 334 1952], and by repeated crystallisation from acetic acid; see Fieser [J Am Chem Soc 75 4395 1953]. Like many sterols, cholesterol gives colour reactions with conc H2SO4: When cholesterol is dissolved in a small volume of CHCl3 and mixed with conc H2SO4, the colour of the organic layer becomes crimson, then changes to purple and on further standing in air it turns to blue, then green and finally yellow. The H2SO4 layer develops a green fluorescence. [Beilstein 6 III 2607, 6 IV 4000.]

비 호환성

Cholesterol is precipitated by digitonin.

Regulatory Status

Included in the FDA Inactive Ingredients Database (injections; ophthalmic, topical, and vaginal preparations).
Included in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
