Low-Density Lipoprotein (LDL) is one of the five major groups of lipoproteins which transport all fat molecules throughout the body in the extracellular water. LDL is often referred to as "bad cholesterol" because high levels can lead to health problems, including cardiovascular diseases. LDL carries cholesterol from the liver to the cells, but when its levels are elevated, it can deposit cholesterol on the walls of blood vessels, leading to atherosclerosis.
