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 ...
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 ...
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 ...
The Pros and Cons of Using Algal Polysaccharides as Prebiotics
(Frontiers Media, 2020)
Macroalgae stand out for their high content of dietary fiber (30-75%) that include soluble, sulfated (fucoidan, agaran, carrageenan, and ulvan) and non-sulfated (laminaran and alginate) polysaccharides. Many studies indicate ...
Minor polysaccharidic constituents from the red seaweed Hypnea musciformis. Appearance of a novel branched uronic acid
(Elsevier, 2017-02)
Two polysaccharide fractions isolated from Hypnea musciformis after room temperature- and hot water extraction, soluble after KCl precipitation of the more abundant carrageenans, were subfractionated by ion-exchange ...
Xylogalactans from Lithothamnion heterocladum, a crustose member of the Corallinales (Rhodophyta)
(Elsevier, 2011-03)
The main polysaccharides from the red seaweed Lithothamnion heterocladum share the general characteristics of corallinans (agar-like xylogalactans), even though this seaweed is crustose, whereas those previously studied ...
Characterization of polysaccharides from cystocarpic and tetrasporic stages of Sub-Antarctic Iridaea cordata
(Elsevier, 2021-12)
The polysaccharide systems from cystocarpic and tetrasporic phases of the Sub-Antarctic algae Iridaea cordata were studied. Cystocarpic plant polysaccharides are mainly composed by carrageenans of the κ–family. However, ...
A sulfated galactan from the mucilaginous sheath of the red filamentous alga Chroodactylon ornatum (Stylonematophyceae, Rhodophyta)
(Springer, 2014-01)
The pseudofilamentous red alga Chroodactylon ornatum was grown in f/2 culture medium with the addition of 10, 34, and 100 μM (nominal concentration) cupric sulfate. The bioassays were terminated at two selected end points ...
