title: The determination of phytosphingosine-containing globotriaosylceramide from human kidney in the presence of lactosylceramide.
abstract: Globotriaosylceramide, the natural substrate of alpha-galactosidase A (the enzyme deficient in Fabry's disease) was prepared from human kidney by repeated medium pressure chromatography on Lichroprep Si 60 (E. Merck) before and after peracetylation. The apparently homogeneous preparation migrating as a single band on HPTLC was analysed by fast atom bombardment mass spectrometry and 1H-NMR at 500 MHz. It was found that in this fraction two major molecular species were comigrating: Gal alpha 1-4Gal beta 1-4Glc beta 1-1ceramide with nervonic and lignoceric acid linked to phytosphingosine and Gal beta 1-4Glc beta 1-1 ceramide with palmitic acid linked to sphingosine.
