Low-density lipoprotein (LDL) is a class of lipoprotein particles that varies in size (18-25 nm in diameter) and contents (while carrying fatty acid molecules in blood and around the body). It is the final stage of VLDL (very low-density lipoprotein) which is produced by the liver. The LDL contains the apolipoproteins B-100 (Apo B-100, a protein with 4536 amino acid residues) ONLY. It also contains antioxidative vitamins (vitamin E or carotinoids). It is commonly referred to as bad cholesterol as high LDL levels can lead to cardiovascular disease.
