CasNo: 57-88-5
Molecular Formula: C27H46O
Appearance: White to faintly yellow cryst. powder
Description |
Cholesterol is a lipid that plays a crucial role in various physiological functions, including cell membrane structure, hormone synthesis, and overall metabolic balance. |
Physical Characteristics |
Appearance: White to faintly yellow crystalline powder. |
Physiological Importance |
Vital for physiological functions but emphasizes the importance of maintaining healthy levels to prevent atherosclerosis and associated cardiovascular risks. |
Distribution in the Body |
A normal person weighing 70 kg contains about 140 grams of cholesterol in the body. |
Roles in the Body |
Formation of cell membranes. |
Cholesterol Transport |
Two major lipoproteins involved in cholesterol transport: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). |
Industrial Uses |
Employed in the production of artificial bezoar and the preparation of hormone drugs. |
Synthesis and Purification |
Commercially obtained from the spinal cord of cattle by extraction with petroleum ethers. |
Definition |
ChEBI: A cholestanoid consisting of cholestane having a double bond at the 5,6-position as well as a 3beta-hydroxy group. |
Hazard |
Questionable carcinogen. |
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. |
storage |
Cholesterol is stable and should be stored in a well-closed container, protected from light. |

… blood cholesterol levels and higher intakes of saturated fatty acids and cholesterol, and US adults have higher blood cholesterol levels and higher rates of CHD morbidity and mortality. …
Excess supply of plant sterol was required in clinical experiments because the material used contained but 75 to 80 per cent of sitosterol and because of the large amount of endogenous cholesterol which has to be inactivated by the sitosterol, besides exogenous cholesterol.
The invention discloses a method for pre...
