Sodium Alginate - PubChem
Sodium Alginate is the sodium salt form of alginic acid and gum mainly extracted from the cell walls of brown algae, with chelating activity. Upon oral administration, sodium alginate binds to and blocks the intestinal absorption of various radioactive isotopes, such as radium Ra 226 (Ra-226) and strontium Sr 90 ( Sr-90 ).

Alginate is a hydrocolloid from algae, specifically brown algae, which is a group that includes many of the seaweeds, like kelps and an extracellular polymer of some bacteria. Sodium alginate is one of the best-known members of the hydrogel group.
Sodium Alginate - an overview | ScienceDirect Topics
Sodium alginate (NaC 6 H 7 O 6) is a linear polysaccharide derivative of alginic acid comprised of 1,4-β-d-mannuronic (M) and α-l-guluronic (G) acids. Sodium alginate is a cell wall component of marine brown algae, and contains approximately 30 to 60% alginic acid.

Structures, properties and application of alginic acid: A review
Nov 1, 2020 · Sodium alginate is composed of two conformational isomer residues: β-d-mannuronic acid (M) and α-l-guluronic acid (G) [42]. In alginate, M and G are homogenously or heterogeneously linked through 1–4 glycosidic bonds, thus forming linear dimers within the larger polymer: homodimers GG and MM occur as do heterodimers MG/GM (Fig. 1). Fig. 1.

The major component of alginate is alginic acid while sodium alginate (SA) is Na-salt of alginic acid, which is a polymer with abundant free hydroxyl and carboxyl groups distributed along the...
Structural Characterization of Sodium Alginate and Calcium Alginate
May 13, 2016 · In this work, we use atomistic molecular dynamics simulation to primarily explore the association and aggregate structure of different alginate chains under various Ca 2+ concentrations and for different alginate chain composition.
Alginates are natural anionic polysaccharides usually salts of alginic acid. They consist of linear copolymers of d-mannuric acid connected by β (1-4) bonds and units of l-guluronic acid connected by β (1-4) bond [1]. Alginates are mainly obtained from …
