Characterization and immunomodulatory activity of sulfated galactan from the red seaweed Gracilaria fisheri. [PDF]

open access: yesInt J Biol Macromol, 2021
Polysaccharides from the red seaweed Gracilaria fisheri possess many functions, which include antioxidant, antiviral, and antibacterial activities. However, detailed data on their immunomodulatory activities are scarce. Here, we isolated sulfated galactans (SG) from G. fisheri. We found that the predominant SG from G.

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

open access: yesAppl Environ Microbiol, 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.

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

open access: yesGlycobiology, 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 ...

Is the antithrombotic effect of sulfated galactans independent of serpin? [PDF]

open access: yesJournal of Thrombosis and Haemostasis, 2014
Sulfated galactans are polysaccharides with heterogeneous structures that frequently show anticoagulant activity. Their anticoagulant mechanisms are complex and distinct from those observed for heparin. Sulfated galactans act through a combination of effects involving serpin-dependent and serpin-independent mechanisms. Interestingly, these polymers can

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.

Antiviral activity of marine sulfated glycans against pathogenic human coronaviruses

open access: yesScientific Reports, 2023
Great interest exists towards the discovery and development of broad-spectrum antivirals. This occurs due to the frequent emergence of new viruses which can also eventually lead to pandemics.

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.

Partial characterization and anticoagulant activity of sulfated galactan from the green seaweed Halimeda opuntia

open access: yesAnais da Academia Brasileira de Ciências, 2023
The number of deaths associated with cardiovascular diseases (CVD) increases every year, leading to an intense search for new compounds that may be employed as anticoagulants.

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 ...
