The Sea as a Rich Source of Structurally Unique Glycosaminoglycans and Mimetics

Microorganisms, 2017
Glycosaminoglycans (GAGs) are sulfated glycans capable of regulating various biological and medical functions. Heparin, heparan sulfate, chondroitin sulfate, dermatan sulfate, keratan sulfate and hyaluronan are the principal classes of GAGs found in ...

Sulfated galactans ameliorate the cellular senescence in dermal fibroblast cells

Journal of Agriculture and Food Research
Replicative senescence of dermal fibroblast is the primary mechanism of intrinsic skin aging. Recent research has focused on the different properties of sulfated galactans (SG) derived from the red seaweed Gracilaria fisheri.

A Sulfated-Polysaccharide Fraction from Seaweed Gracilaria birdiae Prevents Naproxen-Induced Gastrointestinal Damage in Rats

Marine Drugs, 2012
Red seaweeds synthesize a great variety of sulfated galactans. Sulfated polysaccharides (PLSs) from seaweed are comprised of substances with pharmaceutical and biomedical potential.

Antioxidant Sulfated Polysaccharide from Edible Red Seaweed Gracilaria birdiae is an Inhibitor of Calcium Oxalate Crystal Formation

Molecules, 2020
The genus Gracilaria synthesizes sulfated polysaccharides (SPs). Many of these SPs, including those synthesized by the edible seaweed Gracilaria birdiae, have not yet been adequately investigated for their use as potential pharmaceutical compounds ...

ANALYSIS OF Botryocladia occidentalis (RHODOPHYTA) SULFATED GALACTANS AS MODULATORS OF THROMBIN GENERATION [PDF]

Revista Brasileira de Engenharia de Pesca
The cell-wall of Botryocladia occidentalis (Rhodophyta) contains sulfated galactans (BoSGs) with anti- and procoagulant properties, but their effects on thrombin generation (TG) were fewer explored. This study evaluated BoSGs by different extraction times (3, 6, 16 or 24 h) on yield, physical-chemical features and in vitro effects on cephalin-induced ...

Occurrence of sulfated galactans in marine angiosperms: evolutionary implications [PDF]

Glycobiology, 2004
We report for the first time that marine angiosperms (seagrasses) possess sulfated polysaccharides, which are absent in terrestrial and freshwater plants. The structure of the sulfated polysaccharide from the seagrass Ruppia maritima was determined. It is a sulfated D-galactan composed of the following regular tetrasaccharide repeating unit: [3-beta-D ...
