Low-density lipoproteins. Coloured transmission electron micrograph (TEM) of low-density lipoprotein (LDL) particles. LDLs are molecules that are a combination of lipid (fat) and protein and are the form in which lipids are transported in the blood. LDLs transport cholesterol (a steroid) from the liver to the tissues of the body,including the arteries,which has lead to cholesterol transported by LDLs being known as 'bad' cholesterol. Although elevated cholesterol levels are linked to cardiovascular disease,it is vital for the functioning of the body. The treatment for elevated cholesterol involves weight loss,regular exercise and a healthier diet | |
