Sphingomyelin (Egg, Chicken) is widely used in research and pharmaceutical applications due to its role in cell membrane structure and function. It is a key component in studies related to lipid rafts, which are essential for cellular signaling and membrane organization. In the cosmetic industry, it is valued for its moisturizing and skin-barrier-enhancing properties, making it a common ingredient in skincare products. Additionally, it is utilized in the development of drug delivery systems, particularly liposomes, due to its ability to improve stability and bioavailability of encapsulated compounds. Its role in neurological and metabolic research is also significant, as it is involved in processes like apoptosis and cell proliferation.
