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 ...
Partially methylated galactans containing different proportions of 3-O-methyl-galactose from Pleurotus citrinopileatus
(Elsevier B.V., 2018-03-22)
Pleurotus citrinopileatus, popularly known as golden oyster mushroom have medicinal properties, which are attributed mainly to the presence of bioactive polysaccharides. In this work, two partially 3-O-methylated galactans ...
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 ...
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 ...
Structure of highly substituted agarans from the red seaweedsLaurencia obtusa and Laurencia filiformis
(Carbohydrate Polymers, 2015)
Carrageenan and agaran structures from the red seaweed Gymnogongrus tenuis
(Elsevier, 2016-01)
The galactan system biosynthesized by the red seaweed Gymnogongrus tenuis (Phyllophoraceae) is con-stituted by major amounts of /-carrageenans, with predominance of -structures, which were isolatedby extraction with hot ...
Chemical structure and anticoagulant activity of highly pyruvylated sulfated galactans from tropical green seaweeds of the order Bryopsidales
(Elsevier, 2015-05)
Sulfated and pyruvylated galactans were isolated from three tropical species of the Bryopsidales, Penicillus capitatus, Udotea flabellum, and Halimeda opuntia. They represent the only important sulfated polysaccharides ...
Structure of highly substituted agarans from the red seaweeds Laurencia obtusa and Laurencia filiformis
(Elsevier, 2014-01)
The water extracts from red seaweeds Laurencia obtusa and Laurencia filiformis comprise complex sulfated agarans. Those from L. obtusa have 3-linked β-d-galactose units in part sulfated on 2-position or methylated on ...
