Sphingolipids are a class of lipids that play vital roles in cell signaling, membrane structure, and cell-cell interactions. They consist of a long-chain sphingoid base linked to a fatty acid through an amide bond, and are found in high concentrations in cell membranes. Sphingolipids are involved in various biological processes such as cell growth, differentiation, apoptosis, and immune responses. Dysregulation of sphingolipid metabolism has been linked to various diseases including cancer, neurodegenerative disorders, and metabolic disorders. Research in the field of sphingolipids focuses on understanding the complex pathways involved in their synthesis, metabolism, and functions, as well as their potential as therapeutic targets for a range of diseases.
