Description
Sphingosine-d
7 (d18:1) is intended for use as an internal standard for the quantification of sphingosine (d18:1) by GC- or LC-MS. Sphingosine (d18:1) is formed primarily from the breakdown of ceramide.
1 Sphingosine (d18:1) inhibits protein kinase C and phosphatidic acid phosphohydrolase, whereas it activates phospholipase D and diacylglycerol (DAG) kinase.
1 Phosphorylation of sphingosine (d18:1) by sphingosine kinases 1 and 2 (SPHK1, SPHK2) produces sphingosine-1-phosphate, a potent bioactive lipid that exhibits a broad spectrum of biological activities including cell proliferation, survival, migration, cytoskeletal organization, and morphogenesis.

Uses
D-erythro-Sphingosine-d7 is the deuterium labeled D-erythro-Sphingosine. D-erythro-Sphingosine (Erythrosphingosine) is a very potent activator of p32-kinase with an EC50 of 8 μM, and inhibits protein kinase C (PKC). D-erythro-Sphingosine (Erythrosphingosine) is also a PP2A activator[1][2][3][4].
