Benefits of Cholesterol
Cholesterol serves several important roles in metabolism: it is a key constituent of all cell membranes and provides the structural framework of vitamin D and adrenal and sex hormones, as well as for bile acids which help digest fat and increase absorption of fat soluble vitamins. Most cholesterol is made in the liver and is so crucial to metabolism that, if necessary, it can be synthesized from either fatty acids or glucose.
