| Comments |
P.170 right column 2nd paragraph:"Densitometry data on saccharides are reported in [primary source]. From these data, the average monosaccharide, disaccharide and trisaccharide partial molecular volumes are calculated as 184.9(±1.4)x10^-3nm^3 (five values), 346.2(±5.4)x10^-3nm^3 (six values) 507.7(±4.2)x10^-3nm^3 (four values). The differences between these volumes show that the volume of polysaccharide condensation is 23.5 - 23.6x10^-3nm^3. This difference was used to correct the densitometric volumes of the free Glc, Gal and Man carbohydrates to their residue form (Table 3). Since these three volumes are on average 5.4x10^-3nm^3 smaller than those derived from monosaccharide crystal structures (Table 3), densitometric volumes for GlcNAc, GalNAc, Fuc and NeuNAc residues were estimated using this difference to correct the crystal volumes of these residues." |
