Explanation:
Detailed explanation-1: -Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts.
Detailed explanation-2: -Cholesterol is a steroid because it shares the chemical structure of four fused carbon rings with other steroids. Specifically, it is a sterol, which is a class of lipid with an alcohol (hydroxyl) or-OH group.
