CAS 1246303-19-4

1-Oleoyl-N-heptadecanoyl-D-erythro-sphingosine, with the CAS number 1246303-19-4, is a complex sphingolipid that plays a significant role in cellular signaling and membrane structure. This compound features a long-chain fatty acid (oleoyl) and a saturated fatty acid (heptadecanoyl) attached to a sphingosine backbone, which contributes to its amphiphilic nature. The presence of the oleoyl group, a monounsaturated fatty acid, imparts fluidity to membranes, while the heptadecanoyl group, being saturated, can enhance structural stability. Sphingolipids like this one are crucial in various biological processes, including cell recognition, signaling pathways, and the formation of lipid rafts in cell membranes. Additionally, they are involved in neurobiology and can influence the behavior of neurotransmitters. The specific stereochemistry of the D-erythro configuration is important for its biological activity and interaction with other cellular components. Overall, this compound exemplifies the intricate nature of lipid molecules and their essential roles in biological systems.
