Structural Diversity in Galactans From Red Seaweeds and Its Influence on Rheological Properties
(Frontiers Media, 2020-09)
Galactans are important components of many plant cell walls. Besides, they are the major polysaccharides in extracellular matrixes from different seaweeds, and other marine organisms, which have an acidic character due to ...
Gracilariopsis hommersandii, a red seaweed, source of agar and sulfated polysaccharides with unusual structures
(Elsevier, 2019-06-01)
Red seaweed Gracilariopsis hommersandii produces important amounts of non-gelling galactans, which were extracted with hot water (GrC, yield, 37%, viscosity average molecular weight, Mv 109 kDa), comprising agarose and ...
A preponderantly 4-sulfated, 3-linked galactan from the green alga Codium isthmocladum
(Oxford Univ Press Inc, 2008-03-01)
The green algae of the genus Codium have recently been demonstrated to be an important source of sulfated galactans from the marine environment. Here, a sulfated galactan was isolated from the species Codium isthmocladum ...
Charge distribution and calcium affinity of sulfated alpha-L-galactans from ascidians. Comparison between linear and highly branched polymers
(Elsevier B.V., 1998-02-01)
Calcium binding and charge distribution on highly branched and linear sulfated L-galactans from ascidians have been studied using a metallochromic indicator and conductimetric titrations. The distance between charged groups ...
Charge distribution and calcium affinity of sulfated alpha-L-galactans from ascidians. Comparison between linear and highly branched polymers
(Elsevier B.V., 1998-02-01)
Calcium binding and charge distribution on highly branched and linear sulfated L-galactans from ascidians have been studied using a metallochromic indicator and conductimetric titrations. The distance between charged groups ...
Inhibitory effect of sulfated galactans from the marine alga Bostrychia montagnei on herpes simplex virus replication in vitro
(Elsevier Gmbh, 2001-02)
Sulfated polysaccharides exhibit many biological properties such as antiviral and anticoagulant activities. Herein, we report the antiviral activity of sulfated galactans extracted from the red sea-weed Bostrychia montagnei ...
Structural analysis and antiviral activity of a sulfated galactan from the red seaweed Schizymenia binderi (Gigartinales, Rhodophyta)
(Elsevier, 2005-10)
Aqueous extraction of gametophytic Schizymenia binderi afforded a polysaccharide composed of galactose and sulfate groups in a molar ratio of 1.0:0.89 together with uronic acids (6.8 wt %) and minor amounts of other neutral ...
Polysaccharides from Gracilaria corticata: Sulfation, chemical characterization and anti-HSV activities
(Elsevier Science, 2008-11)
In this study, we have analyzed water-extracted polysaccharides of Gracilaria corticata. The water extract (WE), a galactan-containing sub-fraction (F3) and their hyper sulfated derivatives (WES1, WES2, F3S1 and F3S2) had ...
An algal-derived DL-galactan hybrid is an efficient preventing agent for in vitro dengue virus infection
(Georg Thieme Verlag Kg, 2007-11)
The DL-galactan hybrid C2S-3, isolated from the red seaweed Cryptonemia crenulata (Halymeniaceae, Halymeniales), is a potent and selective inhibitor of the multiplication of diverse strains of DENV-2 in Vero cells with ...
