摘要
The concentration of globotriaosylceramide (ceramide trihexoside (CTH)) in the plasma of patients with Fabry disease has been determined quantitatively by tandem mass spectrometry (MS) using novel internal standards, [D4]C-16 CTH and C-17 CTH, which were synthesised enzymically from lyso-CTH using the reverse reaction of sphingolipid ceramide N-deacylase. C-17 CTH was also synthesised chemically from lyso-CTH. This strategy has also been used to prepare standards for the quantitative determination by MS of other glycosphingolipids.
