About the structure and biological function of Sph
What is the structure of Sphingosine?
Sphingosines (sphing-4-enines, sphingenines, D-erythro-sphingosines, or Sph) belong to the group of sphingoid bases within the sphingolipids. Their structure consists of an amino alcohol with a monounsaturated hydrocarbon chain.
What is the function of Sphingosine?
Sphingosines are the most abundant sphingoid bases in sphingolipids of animals and serve an important biological role as biosynthetic precursor to sphingosine-phosphates. As free sphingosines, they interact with specific receptors playing a crucial role in cellular signaling, including growth arrest and cell death. Further, sphingosines are involved in anti-infectious mechanisms against microbial diseases.
