Is there a correlation between structure and anticoagulant action of sulfated galactans and sulfated fucans? [PDF]

open access: yesGlycobiology, 2002
We attempted to identify the specific structural features in sulfated galactans and sulfated fucans that confer anticoagulant activity. For this study we employed a variety of invertebrate polysaccharides with simple structures composed of well-defined units of oligosaccharides.

S-Assimilation Influences in Carrageenan Biosynthesis Genes during Ethylene-Induced Carposporogenesis in Red Seaweed Grateloupia imbricata

open access: yesMarine Drugs, 2022
The synthesis of cell-wall sulfated galactans proceeds through UDP galactose, a major nucleotide sugar in red seaweed, whilst sulfate is transported through S-transporters into algae.

Diversity of Sulfated Polysaccharides From Cell Walls of Coenocytic Green Algae and Their Structural Relationships in View of Green Algal Evolution

open access: yesFrontiers in Plant Science, 2020
Seaweeds biosynthesize sulfated polysaccharides as key components of their cell walls. These polysaccharides are potentially interesting as biologically active compounds.

Trehalose as a Possible Precursor of the Sulfated L-Galactan in the Ascidian Tunic [PDF]

open access: yesJournal of Biological Chemistry, 1995
Among sulfated polysaccharides, those in the tunic of ascidians are unique: their major constituent sugar is galactose, which occurs exclusively in the L-enantiomeric form. Incorporation of D-[14C]glucose into tunic slices in vitro revealed that the cells epimerize D-glucose into L-galactose during biosynthesis of the sulfated polysaccharides.

Structure, biology, evolution, and medical importance of sulfated fucans and galactans [PDF]

open access: yesGlycobiology, 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 ...

Galactans: an overview of their most important sourcing and applications as natural polysaccharides

open access: yesBrazilian Archives of Biology and Technology, 2011
Since last decades, lot of biological and rheological properties of polysaccharides and oligosaccharides were described. Among them, galactans and more especially sulfated galactans from seaweeds have shown interesting and specific properties not only as

A Repeating Sulfated Galactan Motif Resuscitates Dormant Micrococcus luteus Bacteria [PDF]

open access: yesApplied and Environmental Microbiology, 2018
ABSTRACT Only a small fraction of bacteria can autonomously initiate growth on agar plates. Nongrowing bacteria typically enter a metabolically inactive dormant state and require specific chemical trigger factors or signals to exit this state and to resume growth.

Sulfated fucans and a sulfated galactan from sea urchins as potent inhibitors of selectin-dependent hematogenous metastasis [PDF]

open access: yesGlycobiology, 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.

Marine Non-Glycosaminoglycan Sulfated Glycans as Potential Pharmaceuticals

open access: yesPharmaceuticals, 2015
Sulfated fucans (SFs) and sulfated galactans (SGs) are currently the marine non-glycosaminoglycan (GAG) sulfated glycans most studied in glycomics.
