Cholesterol: Significance and Regulation
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes.

Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
