The structure of a galactan sulfate from the red seaweed Bostrychia montagnei

The sulfated, methylated galactan isolated from the red seaweed Bostrychia montagnei, showed an unusually narrow structural dispersion. This agaran has the defining linear backbone of alternating 3-linked β-D-galactopyranosyl units and 4-linked α-L-galactopyranosyl and 3,6-anhydrogalactopyranosyl re...

This agaran has the defining linear backbone of alternating 3-linked β-D-galactopyranosyl units and 4-linked α-L-galactopyranosyl and 3,6-anhydrogalactopyranosyl residues. The D-units have C-6 methylation, C-6 single stubs of xylopyranosyl and minor to trace amounts of (possible) C-6 linked single stubs of galactopyranosyl.
