“…We observed a significant reduction in nitric oxide (Machiavell et al, 2007) production in the presence of high fucan concentrations (above 375 µg/mL). However, we found a bifunctional effect (Yang et al, 2006;Di Rosa et al, 1996), given that low fucan concentrations Like heparin, fucoidans have been shown to affect many biological activities, such as inflammation, cell proliferation and adhesion, viral infection, and fertilization (Linnemann et al, 2000). However, relatively few studies have interpreted the biological activity of fucoidans in terms of molecular structure (Xie et al, 2000).…”
