Such variations in the structural composition of SPs, especially those with high 3,6-anhydrogalactose content and the position of sulfation on their chains, would determine their physical and biological properties (Cardozo et al.
This differentiation in the yield (Tables 1 and 2), as well as in the content of total sugars (Figure 2) varying among extractions could perhaps justify the previous NMR results due to variable intensity of 3,6-anhydrogalactose residues (Figure 1), reflecting also the heterogeneity of these polymers.
The 3,6-anhydrogalactose (3,6-AG) content was determined colorimetrically using the resorcinol-acetal method [20] and fructose as the standard sugar in samples extracted in water or KOH solutions (mass ratio algae/ extracting medium 1 : 20) of various concentrations for 4 h.
In the course of this troublesome study series, which involved purely chemical methods, a unique component sugar, 3,6-anhydrogalactose, was discovered [4] and an idealized extreme structure type of agarose (Fig.
