Cholesterol, only present in animals, belongs to a group of lipids known collectively as sterols.
- Vitamin D required for calcium absorption, bone mineralization, and may be involved in your immune system function, brain and nervous system function, reproductive organs, pancreatic tissue, and skin, muscles and cartilage
- Bile acids which are required for digestion of fats and lipids
- Adrenal hormones such as cortisol which is released in response to stress and acts to increase blood-glucose levels, aldosterone which regulates blood pressure, and epinephrine and norepinephrine which stimulate your flight or fight response
- Steroid sex hormones such as, testosterone, estrogen and progesterone which are key to reproduction and expression of male and female characteristics
- HDL (high density lipoproteins) and LDL (low density lipoproteins)
As well as forming the basis of these compounds cholesterol is a necessary component of cell membranes which accounts for about 90% of all of you body cholesterol.
