<reasoning>
Analyze the biological function of triglycerides
Triglycerides (fats and oils) function primarily as highly concentrated energy reserves in living organisms, yielding more energy per gram than carbohydrates or proteins.
Evaluate the incorrect options
- Membrane stability is primarily maintained by phospholipids and cholesterol, not triglycerides.
- Building new body proteins is the function of amino acids.
- Cell-cell signaling is typically mediated by proteins, glycoproteins, or specific lipid derivatives like steroid hormones, rather than bulk triglycerides.
