LDL particles differ in size and density. In a meta-analysis (of 12 studies), those with oxidized LDL had a higher risk of heart disease. For this reason, oxidized LDL contributes to heart disease. The plaque may grow large enough to restrict blood flow. Ĭholesterol, other fats, and more inflammatory cells can accumulate to form a fatty plaque in the artery. To remove oxidized LDL, inflammatory cells migrate to the artery wall.

Oxidized LDL is toxic to artery wall cells. When LDL gets inside the damaged artery wall to help the healing process, it undergoes a change and becomes oxidized. This helps the artery in the short-term but can be harmful long-term. When arteries become damaged, LDL binds to the artery wall to aid the healing process. LDL binds toxins produced by bacteria ( Staphylococcus) and the toxin lipopolysaccharide ( LPS). Binds certain toxins, making them unable to trigger harmful immune responses.Transfers fat and cholesterol around the body for cells to use.It is the major cholesterol carrier in the body. LDL carries the most cholesterol of all lipoproteins. This is a key step in the development of hardening of the arteries and heart disease. Cholesterol can penetrate arterial walls where it combines with oxygen (oxidizes). LDL- cholesterol is considered the “bad cholesterol” because it deposits in blood vessels. LDL-C forms in the blood when very low-density lipoprotein (VLDL) loses some fat (triglycerides) and becomes denser. VLDL-cholesterol or very-low-density lipoprotein cholesterol is also a “bad” cholesterol.HDL-cholesterol or high-density lipoprotein cholesterol is known as the “good” cholesterol.LDL-cholesterol or low-density lipoprotein cholesterol is known as the “bad” cholesterol.These lipoproteins differ in density (vehicle size): You can think of lipoproteins as the vehicles and cholesterol as the passenger. Ĭholesterol that’s found in the blood is bound into particles called lipoproteins. It’s also used by the body to make steroid hormones (testosterone, estrogens, cortisol, aldosterone etc.), bile, and vitamin D. Continue reading to learn about healthy LDL levels and how to lower LDL without medication.Ĭholesterol is a fat-like substance that’s a key component of cells. However, too much LDL can block blood flow in the arteries and cause heart disease. LDL-Cholesterol, or normally just referred to LDL, transfers fats around the body and supports immune function.
