Alginic acid gels: the effect of alginate chemical composition and molecular weight
TL;DR: The effect of chemical composition and sequence and molecular weight of different alginate samples on the final properties of alginic acid gels have been studied in this paper, where it is shown that alginates with a high content of guluronic acid blocks give gels of a considerably higher strength compared to alginiates rich in mannuronate.
