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.
