How does cholesterol difference from triglycerides in structure and function?

Cholesterol and triglycerides differ in both structure and function. Cholesterol is a sterol, characterized by a ring structure and a hydrophobic tail, playing a key role in cell membrane fluidity and serving as a precursor for steroid hormones and bile acids. In contrast, triglycerides consist of a glycerol backbone bonded to three fatty acid chains, primarily serving as a significant energy storage form in the body. While both are lipids, their distinct structures result in different physiological roles.
