A fucoidan fraction consisting of
l-fucose, sulfate, and acetate in a molar proportion of 1:1.21:0.08 was isolated from the brown seaweed
Fucus distichus collected from the Barents Sea. The
13C NMR spectrum of the fraction was typical of regular polysaccharides containing disaccharide repeating units. According to 1D and 2D
1H and
13C NMR spectra, the fucoidan molecules are built up of alternating 3-linked α-
