Synthesize a scenario where the structural differences between waxes and sphingolipids would result in different biological functions.

Waxes and sphingolipids both act as enzymes in cellular reactions.

Waxes provide water-proofing due to their solid structure, while sphingolipids are involved in cell membrane structure due to their amphipathic nature.

Both waxes and sphingolipids are primarily hormonal precursors.

Waxes and sphingolipids are both used primarily for energy storage.
