Final answer:
Sphingomyeline can form hydrogen bonds through the hydrogen atoms bonded to oxygen or nitrogen atoms in the molecule.
Step-by-step explanation:
Sphingomyeline is a class of sphingolipids that contain a fatty acid, sphingosine, phosphoric acid, and choline. The hydrogen atoms bonded to oxygen or nitrogen atoms in the sphingomyeline molecule can form hydrogen bonds with any oxygen or nitrogen atom. These hydrogen bonds can occur between side chains, backbone groups, or side chains and backbone groups, providing stability to the molecule.
