Structure of fucose branches in the glycosaminoglycan from the body wall of the sea cucumber Stichopus japonicus.


Fucose-branched chondroitin sulfate E was prepared from the body wall of sea cucumber Stichopus japonicus. The purified glycosaminoglycan (GAG) was chemically desulfated, followed by carboxyl reduction. Intact, desulfated, and desulfated/carboxyl-reduced GAG fractions were subjected to per-O-methylation. GC-MS analyses of the resultant partially methylated… (More)
