Cholesterol: My heart’s in danger?
Cholesterol is completely absent in prokaryotes. Liver has the potential to regulate cholesterol levels in the blood. Phytosterols can compete with the absorption of cholesterol in the intestine and thus reduce the cholesterol level. High blood cholesterol can heart disease and angina pectoris. Methods to increase the good cholesterol and lowering cholesterol levels in the blood are cholesterol lowering drugs like statins, fibrates, niacin and bile acid resins. The two main types of cholesterol are high-density lipoprotein (HDL) and low density lipoprotein (LDL). For simplicity, good HDL cholesterol than the while LDL is called bad cholesterol. First Low-density lipoprotein (LDL) or bad cholesterol and its management
LDL or bad cholesterol comprises 60-70% of total serum cholesterol. High concentrations of LDL-cholesterol and low HDL-cholesterol values are associated with the risk of cardiovascular disease. HDL cholesterol is 20-30% of the total cholesterol. Estrogens also increase HDL levels in women with a high level of HDL-cholesterol compared to men.
The reduction of LDL-cholesterol is easier than raising HDL-cholesterol. Can help the ratio of total cholesterol and HDL-cholesterol estimate the risk of atherosclerosis. Third Triglycerides or very low density lipoprotein (VLDL)-cholesterol, or ugly, and their effects
Cholesterol is a lipoprotein-triglyceride ugly, for 10-15% of total serum cholesterol accounts. Oxidosqualene cyclase then converts squalene, lanosterol, finally forming cholesterol. Cholesterol synthesis may be terminated if the cholesterol level is too high. Triglycerides and cholesterol esters are carried internally. LDL molecules are the main carrier of cholesterol in the blood and each molecule contains about 1500 cholesterol esters. HDL molecules to participate in reverse cholesterol transport, as they return cholesterol to the liver for excretion. Breast milk contains sufficient amounts of cholesterol. Plant products such as peanuts and flaxseed are plant sterols are cholesterol-like compounds contribute to lower cholesterol levels in serum. Avoid the consumption of cholesterol-rich animal products not only reduces the amount of cholesterol through diet, but also reduces cholesterol synthesis. Soy protein also protects against heart disease and high cholesterol because it lowers bad cholesterol and increases good cholesterol. Studies have shown, it may order up to 15% of total cholesterol in patients with high cholesterol.
