D-erythro-Sphingosine C-17
Cayman Chemical Item Number 10007902
Description Sphingosine is an amino alcohol most commonly characterized by an 18-carbon unsaturated hydrocarbon chain D-erythro-Sphingosine C-18 (Item No. 10007907). However, the hydrocarbon chain length of sphingosine, and the related dihydrosphingosine, can vary from 12-26 carbons in mammalian tissues.1↗,2↗ D-erythro-Sphingosine C-17 is a naturally-occurring but uncommon form of sphingosine, accounting for approximately 13% of the sphingosine in human skin.1↗ It can be phosphorylated by sphingosine kinases to produce C-17 sphingosine-1-phosphate.3↗ More commonly, sphingosine C-17 is used as an internal standard in the analysis of sphingoid compounds by chromatographic or spectrometric methods.4↗,5↗,6↗
