The data on the probability of fermentation of
fucoidan by intestinal flora are controversial and they
cannot be regarded as definite. The monosaccharide
composition of fucoidans is represented by fucose and
socalled “minor” sugars, such as galactose, xylose,
glucose, and other oligosaccharides in various propor
tions [13, 28]. The fermentative breakage of α1 → 3
bonds between fucose residues in the fucoidan mole
