D-erythro-Sphingosine(CAT: R000424) is a naturally occurring long-chain amino alcohol and a fundamental component of sphingolipids, which are essential structural elements of cell membranes. With the molecular formula C₁₈H₃₇NO₂, it features an unsaturated hydrocarbon chain, a trans double bond, and a primary amine group, giving it both hydrophobic and hydrophilic characteristics. In biological research, D-erythro-sphingosine plays a critical role as a signaling molecule, regulating processes such as apoptosis, cell differentiation, and proliferation. It is also used as a precursor for ceramide and other complex sphingolipids in lipid metabolism studies, making it a key tool in biochemistry, cell biology, and neurobiology research.
