Cholesterol is a fatty-like substance that travels around in your blood and cell membranes. It is required to help protect the integrity of your cells and their fluidity, as well as the myelin sheath that covers them. The liver also converts cholesterol to product bile, which is essential to absorb and digest fat molecules and fat-soluble vitamins such as Vitamins A, D, E & K. Cholesterol is also required to make certain types of hormones such as Estrogen & Testosterone. Cholesterol and fats use particles called "lipoprotein particles" as their method of transportation around the body.
There are two main types of "Lipoprotein."
- Low-Density Lipoprotein (LDL)- often referred to as "bad" cholesterol- carries cholesterol from the liver to the cells
- High-Density Lipoprotein (HDL)- often referred to as "good" cholesterol-returns excess cholesterol to the liver where it is disposed of.
