Cerebroside B is primarily involved in the structure and function of cell membranes, especially in nerve tissue. It plays a key role in the formation and stability of the myelin sheath, which insulates nerve fibers and ensures efficient transmission of nerve impulses. Due to its presence in neural tissues, it is studied for its potential involvement in neurodegenerative disorders and lysosomal storage diseases, such as Gaucher's disease and Krabbe disease, where abnormal accumulation of cerebrosides can lead to cellular dysfunction. In research, Cerebroside B serves as a biomarker for certain metabolic disorders and is used in the development of enzyme replacement therapies. It also has applications in neuroscience for studying cell signaling, membrane dynamics, and neuron-glia interactions. Additionally, it is used in cosmetic and dermatological formulations for its skin barrier-enhancing and moisturizing properties, owing to its role in maintaining epidermal integrity.
