Sphingomyelin (Brain, Porcine) is widely used in research and pharmaceutical applications due to its role in cell membrane structure and function. It is a key component of lipid rafts, which are essential for cellular signaling and membrane organization. In neuroscience, it is utilized to study the biochemical properties of brain cells and their interactions, particularly in understanding neurodegenerative diseases like Alzheimer's and Parkinson's.

In drug delivery systems, sphingomyelin is incorporated into liposomes to enhance stability and improve the targeting of therapeutic agents. It is also used in cosmetic formulations for its moisturizing and skin barrier-strengthening properties. Additionally, sphingomyelin serves as a precursor for bioactive molecules like ceramides, which are studied for their role in apoptosis and cellular regulation. Its applications extend to studying cholesterol metabolism and its impact on cardiovascular health.
