Table 1 Molar composition of monosaccharides in the cell wall fractions

From: Fibres from flax overproducing β-1,3-glucanase show increased accumulation of pectin and phenolics and thus higher antioxidant capacity

  1. The amount of mol of the studied monosaccharides to 100 mol of monosaccharides in the cell wall fractions (WSF – water-soluble fraction, CSF – CDTA-soluble fraction, NSF – Na2CO3-soluble fraction, K1SF – 1 M KOH-soluble fraction and K4SF – 4 M KOH-soluble fraction) for fibres from transgenic flax line B14 and the non-transgenic control flax Nike. Man – mannose, Rha – rhamnose, Glc – glucose, Xyl – xylose, Ara – arabinose, Fuc- fucose, Rib – ribose, Gal – galactose and GalAc – galacturonic acid. Data represents the mean values ± SD from three independent experiments. The significance of the differences between the means was determined using Student’s t test (* - P < 0.05, ** - P < 0.01).
