hdl ldl structure differences
The main structural difference between LDL and HDL is their compositions. Approximately 50 percent of the weight of an LDL particle is cholesterol and only 25 percent is protein.High-density lipoprotein particles, on the other hand, consist of 20 percent cholesterol by weight and 50 percent protein.igh levels of LDL cholesterol or low levels of HDL cholesterol in your bloodstream can increase your risk for heart disease. Optimal LDL cholesterol levels are less than 100 milligrams per deciliter of blood.
Since protein is more dense than fat, HDL particles are more dense than LDL particles, hence the names high-density and low-density lipoproteins. The other major structural difference between LDL and HDL relates to the types of protein they contain.Low-density lipoproteins contain proteins called B-100 proteins, while HDL particles contain mostly A-I and A-II proteins.igh levels of LDL cholesterol or low levels of HDL cholesterol in your bloodstream can increase your risk for heart disease. Optimal LDL cholesterol levels are less than 100 milligrams per deciliter of blood.
