FAQ
Frequently Asked Questions
It is not a fat (triglyceride) itself, but it is a lipid molecule. More specifically, it is the fundamental backbone of a major class of lipids called sphingolipids.
Not as a free molecule in significant amounts. It is a component of complex sphingolipids present in all eukaryotic cell membranes, so it is found in foods containing cellular material, like meat, dairy, and eggs.
Sphingosine-1-phosphate (S1P) is a phosphorylated and metabolically active form of sphingosine. While sphingosine itself can influence cell death, S1P often promotes cell survival and proliferation, acting as a signalling molecule.
The name derives from the 'sphinx', due to the enigmatic nature of these lipids when first discovered. The '-ine' suffix is common in chemistry for amines and alkaloids, reflecting its amino group.
A long-chain amino alcohol that is a primary structural building block of sphingolipids, a major class of lipids found in cell membranes.
Sphingosine is usually technical/scientific in register.
