Verified step by step guidance

Understand the structure of triglycerides: Triglycerides consist of a glycerol backbone attached to three fatty acid chains via ester bonds. They primarily function as energy storage molecules.

Understand the structure of phospholipids: Phospholipids consist of a glycerol backbone, two fatty acid chains, and a phosphate group attached to the third position of glycerol. They primarily function as components of biological membranes.

Compare the classification: Both triglycerides and phospholipids are classified as lipids because they are hydrophobic molecules and share structural similarities.

Compare the composition: Both triglycerides and phospholipids contain fatty acid chains and a glycerol backbone, which are common features of these lipid molecules.

Analyze the functional difference: Triglycerides primarily serve as energy storage molecules, while phospholipids are integral components of biological membranes. This functional distinction highlights why the statement 'Both function primarily as components of biological membranes' is NOT true for triglycerides.
