Which is the highest acceptable mg/dl level of low density lipoprotein (LDL) cholesterol for a child from a family with heart disease? (Record your answer in a whole number.)

110
The low-density lipoproteins (LDLs) contain low concentrations of triglycerides, high levels of cholesterol, and moderate levels of protein. LDL is the major carrier of cholesterol to the cells. Cells use cholesterol for synthesis of membranes and steroid production. Elevated circulating LDL is a strong risk factor in cardiovascular disease. For children from families with a history of heart disease, the LDL should be <110.
