Cholesterol is a derivative of cyclopentan and polyhydrophenanthrene. The chemical formula is C27H46O. It is a white or light yellow crystal. It is the main steroid compound in mammals and plays an important role in basic cell life activities.
Generally, lipids are mainly divided into two categories. Fats (mainly triglycerides) are the most abundant lipids in the human body and are a major source of energy in the body; the other is called lipids, which are the basic components of biological membranes, accounting for about 5% of body weight, except for phospholipids In addition to glycolipids, there is also a very important one called cholesterol.

Cholesterol, a major sterol is the precursor for steroid hormones, bile acid and vitamin in mammals and coordinates endocytosis. It complexes with protein to form lipoproteins for transport in blood. It exists either as high-density lipoprotein (HDL) or low-density lipoprotein (LDL). HDL also called good cholesterol has less lipid content. LDL or bad cholesterol has high lipid content. Statin inhibition of HMG-CoA reductase enzyme in the cholesterol biosynthesis pathway controls elevated cholesterol levels in atherosclerosis and hypercholesterolemia. Low levels of cholesterol results in hypothyroidism, familial hypobetalipoproteinemia and liver disease. Imbalance of cholesterol homeostasis and intracellular cholesterol levels play a key role in cancer development. High cholesterol levels favor breast cancer progression.
