Cholesterol is an important component in the hormonal systems of the body for the manufacture of bile acids, steroid hormones, and vitamin D. Cholesterol is the principal sterol synthesized by animals; in vertebrates it is formed predominantly in the liver. Small quantities are synthesized in other cellular organisms (eukaryotes) such as plants and fungi. It is almost completely absent among prokaryotes (i.e., bacteria).

FUNCTION:
1.Used for flocculent cephalin cholesterol test, vitamin D hormone drugs such as raw materials and biochemical research;
2.Used as a biochemical reagents and emulsifier, etc
3.It's the important raw material for manufacturing hormones, and can be used as emulsifier; Analysis is also used as reference substance
4.Used as emulsifier, artificial bezoar vitamin D LCD synthetic hormones of raw materials, used for biochemical research.
