Low-density lipoproteins are considered as bad cholesterol which circulates throughout the blood streams and they slowly build up within the inner walls of the arteries that connect to the heart and brain. When these low density lipoproteins are combined with other substances, they often form plaque, which can be a thick and hard deposit.
