Cerebrospinal fluid apolipoprotein A1, B100, CⅡ, CⅢ, E

The special protein that makes up lipoproteins is called Apo. Apo is the main protein component that determines the properties of lipoproteins. In different lipoproteins, the type, content and function of Apo are also different. The main functions of Apo are: ① constituting lipoprotein, making plasma lipids soluble ② Activate or inhibit enzymes involved in lipoprotein metabolism. ③ Recognize lipoprotein receptors and bind to specific lipoprotein receptors. ④ Binding and transporting lipids, stabilizing the structure of lipoproteins, etc.
