gsl-bf717
A galactosylceramide with a proposed structure in which an α-galactose residue is linked glycosidically to a sphingoid backbone with substituents ‒C(=O)C<small><sub><em>n</em></sub></small>(OH)H<small><sub>2<em>n</em></sub></small> on nitrogen and ‒C<small><sub>31−<em>n</em></sub></small>(OH)H<small><sub>62−2<em>n</em></sub></small> on C-2. Obtained from the intestinal microbe <em>Bacteroides fragilis</em> NCTC 9343. In the structural diagram R1 = C<small><sub><em>n</em></sub></small>(OH)H<small><sub>2<em>n</em></sub></small> and R2 = C<small><sub>31−<em>n</em></sub></small>(OH)H<small><sub>62−2<em>n</em></sub></small>.
