Alginic Acid, Sodium Salt is a gelling polysaccharide extracted from giant brown seaweed. It is a straight chain, colloidal, polyuronic acid composed mainly of anhydro-b-D-mannuronic acid residues linked in the 1---->4 position. Alginic acid sodium is a gelling and nontoxic anionic polysaccharide. The carboxylic acid groups on the alginic acid chain, renders it insoluble in water. However, converting alginic acid to its sodium form, enables it to solubilize in water easily.
Alginic Acid, Sodium Salt has been used in the flocculation of solids in water treatment; as sizing agent; thickener; emulsion stabilizer; and a suspending agent.
Alginic acid sodium is used:
- in combination with chitosan, to fabricate a biodegradable porous scaffold for bone tissue engineering.
- to study the characteristics of a modified amphiphilic alginate derivative
- to the study the impact of alginate on the rate of lipid digestion using an in vivo digestion model
- in the preparation of alginate hydrogels with tunable mechanical properties
- as encapsulating agents of microparticles of β-galactosidae
- to study the effect of alginate entrapped cells of Pseudomonas stutzeri on the degradation of naphthalene.
