Alginic acid, M.W. ~240,000 (from Macrocystis pyrifera (kelp)), off-white powder
Supplier: MP Biomedicals
A straight-chain, hydrophilic, colloidal, polyuronic acid composed primarily of anhydro-β-D-mannuronic acid residues with 1→4 linkage.
Alginic acid is suitable reagent used to study the in-vitro and in-vivo mitogenic activity of alginates. It is suitable for use in the spectrophotometric determination of transparent exopolymer particles by dye-binding assay.
It is reported to inhibit the reverse transcriptase activity of HIV. Structural investigation of alginic acid, a marine algal polysaccharide poly-α-L-guluronic acid, has been reported. Anti-inflammatory effect of alginic acid, isolated from the brown algae Sargassum wightii, in type II collagen induced arthritic rats has been reported. Pyrolysis of alginic acid using py-GC/MS over a wide temperature range (200-800°C) and thermogravimetric analysis (TGA) has been reported. It was reported to cause the biocorrosion of thin films of copper on germanium internal reflection elements (IREs).
Insoluble, but swells in water; slightly soluble in alkalis [soluble in 0,1 M NaOH].
