Effect of red seaweed sulfated galactans on initial steps of complement activation in vitro. [PDF]
Carbohydr Polym, 2021 The research described here presents data on the effect of galactans of red algae, carrageenans (λ/μ/ν-, κ-, κ/β-, and ι/κ-types), and agar on complement system activation in normal human serum. The experiments were based on well surfaces coated with triggering agents for binding initiating complement components -C3 and C4.

Galactans: an overview of their most important sourcing and applications as natural polysaccharides
Brazilian Archives of Biology and Technology, 2011 Since last decades, lot of biological and rheological properties of polysaccharides and oligosaccharides were described. Among them, galactans and more especially sulfated galactans from seaweeds have shown interesting and specific properties not only as

Structural Diversity in Galactans From Red Seaweeds and Its Influence on Rheological Properties [PDF]
Frontiers in Plant Science, 2020 Galactans are important components of many plant cell walls. Besides, they are the major polysaccharides in extracellular matrixes from different seaweeds, and other marine organisms, which have an acidic character due to the presence of sulfate groups ...

The Protective Role of Sulfated Polysaccharides from Green Seaweed Udotea flabellum in Cells Exposed to Oxidative Damage [PDF]
Marine Drugs, 2018 Seaweed is a rich source of bioactive sulfated polysaccharides. We obtained six sulfated polysaccharide-rich fractions (UF-0.3, UF-0.5, UF-0.6, UF-0.7, UF-1.0, and UF-2.0) from the green seaweed Udotea flabellum (UF) by proteolytic digestion followed by ...
