Here are the essential concepts you must grasp in order to answer the question correctly.
Steroids
Steroids are a class of lipids characterized by a structure of four fused carbon rings. They play various roles in biological systems, including serving as hormones (like testosterone and estrogen) and components of cell membranes. Cholesterol, specifically, is a type of steroid that is crucial for maintaining membrane fluidity and serves as a precursor for the synthesis of other steroids.
