Concept explainers
To explain: The necessity to break the total serum cholesterol level into an LDL and HDL component.
Concept introduction: Cholesterol is a fatty substance required by our body to make hormones, vitamin D, and bile acids to aid the digestion. It is also needed to build and maintain the cell’s outer wall. It cannot dissolve in the blood and therefore, it is carried around by proteins. These fat and protein complexes are called lipoproteins.
To determine: The levels of LDL cholesterol and HDL cholesterol that are considered as normal.
