A comprehensive review of sulfated fucan from sea cucumber: Antecedent and prospect
Carbohydrate PolymersSulfated fucan from sea cucumber is mainly consists of L-fucose and sulfate groups. Recent studies have confirmed that the structure of sulfated fucan mainly consists of repeating units, typically tetrasaccharides. However, there is growing evidence indicating the presence of irregular domains with heterogeneous units that have not been extensively ...

Polysaccharides from the brown seaweed Padina tetrastromatica: Characterization of a sulfated fucan
Carbohydrate Polymers, 2009Sulfated fucans, the complex polysaccharides from brown seaweeds, possess various biological activities. To understand the structure activity relationship of sulfated fucans, we have investigated the structural features of one such polymer from Padina tetrastromatica using standard methods of carbohydrate structural analysis.

AbstractThe sulfated fucan from the sea urchin Lytechinus variegatus is composed of the repetitive sequence [‐3)‐α‐l‐Fucp‐4( )‐(1‐3)‐α‐l‐Fucp‐2,4‐di( )‐(1‐3)‐α‐l‐Fucp‐2( )‐(1‐3)‐α‐l‐Fucp‐2( )‐(1‐]n. Conformation (of rings and chains) and dynamics of this tetrasaccharide‐repeating sulfated fucan substituted by Na+, Ca2+, and Li+ as counterions have been

Methylation analysis of a fucose-containing, sulfated polysaccharide (C-II), which was isolated from the brown seaweed Ecklonia kurome and has a potent anticoagulant activity, showed the presence of 3-O- and 3,4-O-disubstituted fucopyranosyl residues in addition to small proportions of nonreducing, terminal fucofuranosyl and fucopyranosyl groups, and 2,

A fucan sulfate was isolated and purified from the sea cucumber Holothuria albiventer by papain enzymolysis, alkaline hydrolysis and ion-exchange chromatography. The water-soluble polysaccharide had high molecular weight and contained fucose and sulfate in a molar ratio of about 1:0.83.

The antithrombin effects of the sub-fractionated fucans with different molecular weights and sulfate contents, which were prepared from a fucan sulfate isolated from the brown seaweed Ecklonia kurome, were examined for their abilities to inhibit thrombin-fibrinogen reaction and amidolytic activity of thrombin, and to bind to fibrinogen.

Desulfation of a fucoidan from Saccharina japonica by treatment with DMSO-MeOH resulted in partial degradation of polymeric molecules by methanolysis giving rise to a mixture of neutral, monosulfated, and disulfated fucooligosaccharides in the form of methyl glycosides. These oligomeric fragments were characterized by ESI-MS and ESI-CID-MS/MS.

Zinc specifically stimulates the selective binding of a peptide analog of bindin to sulfated fucans.
Peptide research, 1992A synthetic nonapeptide (Leu-Arg-His-Leu-Arg-His-His-Ser-Asn) derived from the sequence of the sea urchin sperm adhesive protein, bindin, has been shown to bind sulfated fucans in high ionic strength (seawater) conditions. The binding is enhanced by approximately 100-fold in the presence of zinc ions, and no other transition metal tested demonstrates ...
