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.
