Lipoprotein
Soluble lipoprotein plays an important role in the transport of plasma lipoproteins in lipids in animals. Lipids in lipoproteins can also interact with components of cell membranes and participate in the regulation of cellular lipid metabolism; in addition, plasma lipoproteins and arteries There is a close relationship between atherosclerotic cardiovascular diseases, and low lipoprotein blood and high lipoprotein blood are also diseases of abnormal plasma lipoprotein. Insoluble lipoproteins are the major components of various biofilms, such as cell membranes and organelle membranes. The protein component within lipoproteins is called apolipoprotein. The synthesis and secretion of high density lipoproteins is carried out in the liver and intestine. Disorders in any part of human lipoprotein metabolism can lead to hyperlipidemia or hyperlipoproteinemia. High-density lipoprotein: It carries cholesterol in surrounding tissues, which is then converted to bile acids or directly excreted from the intestines through bile. Angiography has shown a significant negative correlation between high-density lipoprotein cholesterol levels and arterial lumen stenosis. Therefore, high-density lipoprotein is an anti-atherosclerotic plasma lipoprotein and a protective factor for coronary heart disease. Commonly known as "vascular scavenger." Very low density lipoprotein: transports endogenous triglycerides synthesized in the liver. Triglycerides can be synthesized in hepatocytes, whether they are fatty acids transported by blood to liver cells or fatty acids formed by the conversion of sugar metabolism. In hepatocytes, glycerol H ester binds to APOB100, cholesterol, etc. to form VLDL and is released into the blood. In a low-fat diet, the intestinal mucosa also secretes some VLDL human blood. Most of the metabolism of VLDL human blood becomes low density lipoprotein (LDL). Since VLDL is metabolized slowly in blood and has a half-life of 6 to 12 hours, there is still a certain amount of VLDL in fasting blood. VLDL does not easily penetrate the inner membrane of the artery because it carries relatively little cholesterol and their particles are relatively large. Therefore, normal VLDL generally does not have an atherogenic effect. However, since glycerol triglyceride in VLDL accounts for 50% to 70% and cholesterol accounts for 8% to 12%, once VLDL levels are significantly increased, in addition to elevated triglycerides in plasma, cholesterol levels also increase. Lipoprotein a is mainly synthesized in the liver, and its main function is to prevent blood clots from damaging and promote the formation of atherosclerosis. The continuous increase of lipoprotein levels is closely related to angina pectoris, myocardial infarction and cerebral hemorrhage. Is an independent risk factor for coronary heart disease Clinical significance of lipoprotein a (Lp-a): Increased: seen in atherosclerotic cardio-cerebral vascular disease, acute myocardial infarction, familial hypercholesterolemia, diabetes, large aneurysms and certain cancers. Reduced: seen in liver disease, alcohol abuse, intake of neomycin and other drugs.
