Q: What role does cholesterol play in the human body?
A: Cholesterol is an essential component of the human body, playing a key role in hormone production and digestion. It helps to form a protective barrier around cells in the body, as well as aiding in the production of bile acids, which are necessary for the digestion of dietary fats. Cholesterol is also an important precursor for the production of some hormones, such as testosterone, estrogen, and progesterone. In addition, cholesterol helps to regulate the levels of other hormones, such as cortisol and adrenaline, and can play a role in maintaining healthy blood pressure levels.
