Why does the body produce cholesterol?

Answer 1

Cholesterol is essential for:

• Formation and maintenance of cell membranes (helps the cell to resist changes in temperature and protects and insulates nerve fibers.)
• Formation of sex hormones (progesterone, testosterone, estradiol, cortisol)
• Production of bile salts, which help to digest food.
• Conversion into Vitamin D in the skin when exposed to sunlight.
