Cholesterol CAS#57-88-5
Cholesterol CAS#57-88-5
Cholesterol is a type of steroid substance that is widely present in animal bodies. It plays an indispensable role in human physiological activities, and at the same time has extremely high application value in the pharmaceutical and cosmetics industries. At room temperature, it appears as colorless, white or slightly yellowish, flaky crystals. Its melting point is approximately 148℃. Its chemical properties are quite stable and are not significantly affected by processing factors such as acids, bases, and heat.

Hazardous Substances Data | 57-88-5(Hazardous Substances Data) |
Toxicity | Present in all parts of the animal body; concentrated in spinal cord, brain, skin secretions, and gallstones. An unsaturated, unsaponifiable alcohol (m.p. 149℃). It is synthesized in the body from ethanoate units; its metabolism is regulated by a specific set of enzymes. It is the parent compound of many other steroids and its presence in high concentrations in the blood is suspected as being a contributory factor in cardiovascular disease. |
