A polysaccharide composed of L-fucose, D-xylose, and sulfate in a molar proportion of about 5:2:3 was isolated from the brown alga Punctaria plantaginea. Polysaccharide structure was elucidated by methylation analysis, Smith degradation, as well as by 1D and 2D NMR spectroscopy. The polysaccharide was shown to contain a backbone of 3-linked α-L-fucopyranose residues, about two thirds of which are sulfated at O-2 forming trisaccharide repeating units →3)-α-L-Fucp2S-(1→3)-α-L-Fucp2S-(1→3)-α-L… 
A sulfated galactofucan from the brown alga Hormophysa cuneiformis (Fucales, Sargassaceae).
TLDR
F3 acts as anticoagulant and is about half as active as the standard low-molecular mass heparin (enoxaparin).
Polysaccharides of algae 67. Carrageenan from Pacific red alga Turnerella mertensiana (Gigartinales, Rhodophyta)
A sulfated galactan composed of nearly equimolar amounts of d-galactose, 3,6-anhydro-d-galactose, and sulfate was isolated from the red alga Turnerella mertensiana collected in the Sea of Japan. The
Ion-exchange purification and structural characterization of five sulfated fucoidans from brown algae
TLDR
Ion-exchange chromatography efficiently removes the polysaccharides alginate and laminarin and other contaminants such as proteins and phlorotannins across a broad range of fucoidans from major brown algal orders including Ectocarpales, Laminariales and Fucales.
Anticoagulant and antithrombotic activities of modified xylofucan sulfate from the brown alga Punctaria plantaginea.
TLDR
The effect of sulfated fucans on thrombin inhibition, which was similar to those of heparinoid Clexane(®) (enoxaparin) and of a fucoidan from the brown alga Saccharina latissima studied previously, can be explained by the multicenter interaction and formation of a ternary complexThrombin-antithrombin III-polysaccharide.
Identification, classification, and evolution of putative xylosyltransferases from algae
TLDR
This study identifies 30 XylTs from primary endosymbionts and proposes that FucXylTs originated from the last eukaryotic common ancestor, rather than being plant specific, because they are also distributed in Choanoflagellatea and Echinodermata.
Is the transformation of fucoidans in human body possible?
Structural characterization and antitumor effects of fucoidans from brown algae Kjellmaniella crassifolia farmed in northern China.
TLDR
Oral administration of F at a dose of 450 mg/kg d significantly inhibited lump growth in Hca-F-inoculated mice and led to upregulated FAS expression in tumor tissues compared to that of the control, while F1 and F2 did not show competitive antineoplastic efficacy, as did the crude extract.
Fucoidan Characterization: Determination of Purity and Physicochemical and Chemical Properties
TLDR
The current article highlights the different spectrometric and nonspectrometric methods applied for the characterization of native fucoidans, including degree of purity, sugar monomeric composition, sulfation pattern and content, molecular mass, and glycosidic linkages.
A Comprehensive and Comparative Analysis of the Fucoidan Compositional Data Across the Phaeophyceae
In the current review, compositional data on fucoidans extracted from more than hundred different species were surveyed through the available literature. The analysis of crude extracts, purified

A study of fucoidan from the brown seaweed Chorda filum.
TLDR
Other fucoidan fractions from C. filum have more complex carbohydrate composition and give rather complex methylation patterns, which correspond to a quasiregular polysaccharide structure with a branched hexasaccharide repeating unit.
A sulfated glucuronofucan containing both fucofuranose and fucopyranose residues from the brown alga Chordaria flagelliformis.
TLDR
The fucoidan was shown to contain a backbone of 3-linked alpha-l-fucopyranose residues, about one-third of which are glycosylated at C-2 by alpha-d-glUCopyranosyluronic acid residues.

TLDR
The xylofucoglucuronan has low anticoagulant and no hemorrhagic activity but, as heparin, has a high activity in stimulating the synthesis of an antithrombotic heparan sulfate from vascular endothelial cells in culture.

TLDR
