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 ).
Alginic acid - Wikipedia
Alginic acid, also called algin, is a naturally occurring, edible polysaccharide found in brown algae. It is hydrophilic and forms a viscous gum when hydrated. When the alginic acid binds with sodium and calcium ions, the resulting salts are known as alginates. Its colour ranges from white to yellowish-brown.
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.

2022年5月29日 · 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.
Alginate: properties and biomedical applications - PMC
Amphiphilic derivatives of sodium alginate have been prepared by conjugation of long alkyl chains (i.e., dodecyl, octadecyl) to the alginate backbone via ester bond formation. Aqueous solutions of these alginate derivatives exhibited the typical rheological properties of physically cross-linked, gel-like networks in the semidilute regime, which ...

For example, Yao [17] found that gelatin and sodium alginate composite hydrogels performed well in wound healing through in vitro models of secretion system experiments. Alginate for scaffold fabrication and stem cell regeneration has been a hot research topic in recent years [18].
Sodium alginate: an overview - ScienceDirect
2023年1月1日 · Sodium alginate (NaC 6 H 7 O 6) n is an anionic straight chain polysaccharide. It is composed of repeating units of L-guluronic acid and D-mannuronic acid residues linked together via 1–4 glycosidic linkage. The source of sodium alginate is the seawater brown algae and is present in the outermost covering, the cell wall of the algae.
