Polysaccharides from the green seaweeds Codium fragile and C. vermilara with controversial effects on hemostasis
Codium fragile and Codium vermilara biosynthesize water-soluble sulfated arabinans and galactans (and/or sulfated arabinogalactans), α(1 → 4)-d-glucans and β(1 → 4)-d-mannans. The former polysaccharides are composed by 3-linked β-d-galactopyranose and β-l-arabinopyranose residues, they are highly su...
