Chemical structures of three fucogangliosides isolated from nervous tissue of mini-pig

Eur J Biochem. 1981 Jun 1;116(3):553-64. doi: 10.1111/j.1432-1033.1981.tb05372.x.

Abstract

In the nervous tissue of miniature pig, type Göttingen, three fucosyl-containing gangliosides are major gangliosides. All three were found in dorsal-root ganglia and spinal cord, but only two of them in the forebrain. The concentrations of these gangliosides were increased in chloroquine intoxication. Their chemical structures were determined by component analysis, partial acid and enzymatic degradation and assay of the partially methylated sugars after hydrolysis, reduction and acetylation. Mass spectrometric analysis of the intact gangliosides as permethylated, permethylated-reduced and permethylated-reduced-silylated derivatives confirmed the following structures of the three gangliosides.
