Sulfated fucans, fresh perspectives: structures, functions, and biological properties of sulfated fucans and an overview of enzymes active toward this class of polysaccharide [PDF]
Glycobiology, 2003 Sulfated fucans, frequently referred to simply as fucans, constitute a class of polysaccharides first isolated in 1913. For many years fucans were regarded only as a potential source of l-fucose, although their anticoagulant activity was known. Even as the potent effects of fucans on physiological systems have become better characterized, structural ...

Secretion of sulfated fucans by diatoms may contribute to marine aggregate formation [PDF]
Limnology and Oceanography, 2021 AbstractMicroalgae produce copious amounts of structurally diverse polysaccharides, some are bound within cells and cell walls, while others are secreted into the surrounding seawater. A fraction of the secreted polysaccharides assembles into particles promoting aggregation and in turn formation of aggregates increases the export of carbon into the ...

Structure, biology, evolution, and medical importance of sulfated fucans and galactans [PDF]
Glycobiology, 2008 Sulfated fucans and galactans are strongly anionic polysaccharides found in marine organisms. Their structures vary among species, but their major features are conserved among phyla. Sulfated fucans are found in marine brown algae and echinoderms, whereas sulfated galactans occur in red and green algae, marine angiosperms, tunicates (ascidians), and ...

Molecular Plant-Microbe Interactions, 2003 Sulfated fucans are common structural components of the cell walls of marine brown algae. Using a fucan-degrading hydrolase isolated from a marine bacterium, we prepared sulfated fucan oligosaccharides made of mono- and disulfated fucose units ...

Sulfated fucans and a sulfated galactan from sea urchins as potent inhibitors of selectin-dependent hematogenous metastasis [PDF]
Glycobiology, 2018 Metastasis is responsible for the majority of cancer-associated deaths, though only a very small number of tumor cells are able to efficiently complete all the steps of that process. Tumor cell survival in the bloodstream is one of the limiting aspects of the metastatic cascade.

Food Frontiers, Volume 4, Issue 4, Page 1547-1560, December 2023., 2023 Brown seaweed polysaccharides (BSP) exerted many benefits in enhancing the integrity and function of the intestinal epithelium barrier and modulating gut microbiota composition. The main mechanisms involved in BSP‐associated beneficial activities included reducing intestinal oxidative stress and inflammation, ameliorating TJs dysfunction, increasing ...

Marine organism sulfated polysaccharides exhibiting significant antimalarial activity and inhibition of red blood cell invasion by Plasmodium [PDF]
, 2016 The antimalarial activity of heparin, against which there are no resistances known, has not been therapeutically exploited due to its potent anticoagulating activity.
