title: A sulfated alpha-L-fucan from sea cucumber.
abstract: A purified sulfated alpha-L-fucan from the sea cucumber body wall was studied, before and after almost complete desulfation, using methylation analysis and NMR spectroscopy. NMR analysis indicates that 2,4-di-O-sulfo-L-fucopyranose and unsubstituted fucopyranose are present in equal proportions, and that 2-O-sulfo-L-fucopyranose is present in twice that proportion. There is some NMR evidence that a regular repeating sequence of four residues comprises most or all of the polysaccharide chain.
