Carrying Cholesterol around the Body

Cholesterol is insoluble in the blood so it is transported to cells and tissues using special blood protein called lipoproteins.

  • Low Density Lipoproteins (LDL) carry cholesterol from the liver to the cells and tissues
  • High Density Lipoproteins (HDL) carry excess cholesterol that is not needed by the body back into to liver
