Widely used in cell culture applications, particularly in studies involving cell signaling, apoptosis, and cell proliferation. Plays a key role in sphingolipid metabolism research due to its function as a precursor to bioactive sphingolipids such as ceramide and sphingosine-1-phosphate. Commonly utilized in neuroscience research for modeling lipid-related pathways in neuronal and glial cells. Also employed in dermatological studies for skin barrier function and epidermal differentiation due to its presence in natural skin lipids. Frequently added to growth media for specialized cell types requiring lipid supplements for optimal growth and function. Additionally, serves as a standard in the analysis of sphingolipids in biological samples.
