Is it true that cholesterol belongs to a group of lipids called steroids?

Cholesterol is indeed part of a group of lipids known as steroids. Steroids are characterized by their four-ring structure, and cholesterol is a fundamental steroid that plays vital roles in cell membrane structure, fluidity, and the synthesis of steroid hormones. Being classified as a lipid, cholesterol is hydrophobic and insoluble in water, but it plays critical roles in various biological functions, including cellular signaling and serving as a precursor for the synthesis of bile acids and steroid hormones. Therefore, stating that cholesterol belongs to the group of lipids called steroids is accurate.
