Definition for Low-density lipoprotein
From Biology Forums Dictionary
Low-density lipoprotein (LDL) is one of the five major groups of lipoproteins. Studies have shown that higher levels of type-B LDL particles (as opposed to type-A LDL particles) are associated with health problems, including cardiovascular disease. LDL is often informally called bad cholesterol, while high-density lipoproteins are frequently referred to as good cholesterol or healthy cholesterol.
