How do ldl and hdl differ functionally

Because of this, your body must pair cholesterol with proteins, making a complex called a lipoprotein, to transport cholesterol through your bloodstream to cells that need it for various functions. Although LDL and HDL both play roles in transporting cholesterol within your body, they have very different structures, functions and effects on your health.

All types of lipoproteins contain both lipids and proteins, but the relative composition of each lipoprotein varies.

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. Since protein is more dense than fat, HDL particles are more dense than LDL particles, hence the names "high-density" and "low-density" lipoproteins.

Maintaining healthy levels of cholesterol is manageable. Medication is key, along with eating a healthy diet with lots of vegetables and getting regular exercise. The experts at the USC CardioVascular Thoracic Institute can help you understand your count and give you the support you need to maintain cholesterol levels needed for a healthy heart.

Also Know, what are the functions of LDL? Low-density lipoprotein Low-density lipoprotein LDL is one of the five major groups of lipoprotein which transport all fat molecules around the body in the extracellular water. Lipoproteins transfer lipids fats around the body in the extracellular fluid, making fats available to body cells for receptor-mediated endocytosis. HDL takes the "bad," LDL low density lipoprotein cholesterol out of your blood and keeps it from building up in your arteries.

LDL cholesterol is known as bad cholesterol because it leads to the development and build up of plaque on the walls of your arteries. A cholesterol test, or screening, tells your health care provider the levels of LDL and HDL cholesterol in your blood. This information helps your health care team determine your risk for heart disease or stroke.

Plaque is made up of cholesterol deposits. Lipoproteins are made of fat and proteins. Cholesterol moves through your body while inside lipoproteins. HDL helps rid your body of excess cholesterol so it's less likely to end up in your arteries. What should LDL be? A few changes in your diet can reduce cholesterol and improve your heart health: Reduce saturated fats.
