Lipoproteins & Cholesterol Transport

what are the major types of lipoproteins?

4 main types of lipoproteins

• Chylomicrons

• VLDL (Very-Low-Density Lipoproteins)

• LDL (Low-Density Lipoproteins)

• HDL (High-Density Lipoproteins)

what are the basic differences in the composition and function of HDL and LDL?

• The blood lipid linked most directly to heart disease is LDL cholesterol

• HDL remove cholesterol from the cells and carry it back to the liver for recycling or disposal.

• LDL half cholesterol

• HDL half protein

how does HDL participate in transporting cholesterol back to the liver?

• The liver makes HDL (high-density lipoproteins) to remove cholesterol from the cells and carry it back to the liver for recycling or disposal.

• By efficiently clearing cholesterol, HDL help prevent plaque buildup, thereby lowering the risk of heart disease

what is the relationship between LDL cholesterol and cardiovascular health?

The blood lipid most directly linked to heart disease is LDL cholesterol

• Plaque Buildup: Excess LDL particles in the bloodstream can infiltrate the inner walls of your arteries, where they become oxidized and trapped.

• Atherosclerosis: The trapped cholesterol triggers an immune response, leading to the formation of hard, narrow deposits called atherosclerotic plaques.

• Clots and Events: Over time, these plaques can grow, restrict blood flow, or rupture, causing blood clots that trigger heart attacks and strokes
