Verified step by step guidance

Understand the structure of glycerol: Glycerol is a three-carbon alcohol with hydroxyl (-OH) groups attached to each carbon. It serves as a backbone for certain lipid molecules.

Learn about triglycerides: Triglycerides are composed of one glycerol molecule bonded to three fatty acid chains through ester bonds. This makes glycerol the backbone of triglycerides.

Examine cholesterol esters: Cholesterol esters consist of cholesterol and a fatty acid linked by an ester bond. They do not use glycerol as a backbone.

Analyze sphingolipids: Sphingolipids are based on a sphingosine backbone, which is an amino alcohol, not glycerol. Therefore, glycerol is not involved in their structure.

Review steroids: Steroids are composed of a fused ring structure (cyclopentanoperhydrophenanthrene) and do not contain glycerol as a backbone. They are structurally distinct from glycerol-based lipids.
