D-erythro-C18-Dihydro-D-sphingosine(CAT: R020718), also known as sphinganine, is a saturated long-chain amino alcohol and a key intermediate in sphingolipid metabolism. It consists of an 18-carbon backbone with hydroxyl groups at C1 and C3 and an amino group at C2, in the D-erythro configuration. Unlike sphingosine, it lacks a trans double bond, giving it a fully saturated structure. This compound plays a crucial role in the biosynthesis of ceramides and complex sphingolipids, which are vital for cell membrane structure and signaling. D-erythro-C18-Dihydro-D-sphingosine is widely used in biochemical research related to skin barrier function, apoptosis, and lipid metabolism.
