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 ...
Effects of sulfated and non-sulfated β-glucan extracted from Agaricus brasiliensis in breast adenocarcinoma cells – MCF-7
(2015)
The β-glucans (β-G) are polysaccharides produced by various organisms, and sulfation of β-G renders them more soluble. With the objective to assess the effects of sulfated and non-sulfated β-G extracted from Agaricus ...
Chemically sulfated arabinoxylans from Plantago ovata seed husk: Synthesis, characterization and antiviral activity
(Elsevier, 2021-03)
Limited options for the treatments of diseases triggered through viral infections revealed the quest for novel antiviral drugs. Polysaccharide sulfates owing to their unique mode of action are prominent antiviral drug ...
INCREASED CALCIUM AFFINITY OF A FUCOSYLATED CHONDROITIN SULFATE FROM SEA-CUCUMBER
(Elsevier B.V., 2014)
Pb(II) and Cd(II) biosorption on Chondracanthus chamissoi (a red alga)
(Elsevier, 2011)
Chondracanthus chamissoi is an efficient biosorbent for Pb(II) and Cd(II). The sorption efficiency increases with pH and reaches an optimum around pH 4. Maximum sorption capacity reaches 1.37mmolPbg-1 and 0.76mmolCdg-1. ...
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 ...
Efeito da salinidade da água do mar no rendimento, composição e atividades biológicas de frações polissacarídicas da Chlorophyta Caulerpa cupressoides var. flabellata
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em BioquímicaBioquímica; Biologia Molecular, 2010-03-19)
Seaweeds sulfated polysaccharides have been described as having various pharmacological activities. However, nothing is known about the influence of salinity on the structure of sulfated polysaccharides from green seaweed ...
Monthly fluctuations in the content and monosaccharide composition of fucoidan from Undaria pinnatifida sporophylls from northern Patagonia
(Springer, 2021-05-17)
The invasive brown seaweed Undaria pinnatifida was first recorded in 1992 in Golfo Nuevo, northern Patagonia, Argentina (hereafter Undaria). Like other brown seaweeds, Undaria synthesizes fucoidans, a unique class of ...
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 ...
