Sphingosine (2-amino-4-octadecene-1,3-diol) is an 18-carbon amino alcohol with an unsaturated hydrocarbon chain, which forms a primary part of sphingolipids, a class of cell membrane lipids that include sphingomyelin, an important phospholipid. ==Functions== Sphingosine can be phosphorylated in vivo via two kinases, sphingosine kinase type 1 and s...

<biochemistry> Long chain amino alcohol that bears an approximate similarity to glycerol with a hydrophobic chain attached to the 3 carbon. Forms the class of sphingolipids when it carries an acyl group joined by an amide link to the nitrogen. Forms sphingomyelin when phosphoryl choline is attached to the 1 hydroxyl group.

Long-chain amino alcohol that bears an approximate similarity to glycerol with a hydrophobic chain attached to the 3-carbon. Forms the class of sphingolipids when it carries an acyl group joined by an amide link to the nitrogen. Forms sphingomyelin when phosphoryl choline is attached to the 1-hydroxyl group. Gives rise to the cerebroside and ganglioside classes of glycolipids when oligosaccharides are attached to the 1-hydroxyl group. Not found in the free form.
