LDL receptor
The LDL receptor is a protein found on the surface of cells that helps regulate cholesterol levels in the bloodstream. LDL stands for low-density lipoprotein, which is often referred to as "bad" cholesterol. The receptor binds to LDL particles in the blood and removes them from circulation, allowing cells to take in cholesterol needed for functions like producing hormones and maintaining cell membranes. By controlling the amount of cholesterol in the blood, LDL receptors play a vital role in preventing heart disease and maintaining cardiovascular health.
