Chemical properties of sodium alginate

Chemical properties
Sodium alginate (C6H7O8Na) n mainly by the sodium salt of alginic acid composition, the aL-mannose acid (M units) and bD-old Luo uronic acid (G unit) rely on 1,4 - glycosidic linkage by different proportion of GM, MM and GG fragments of the copolymer.

Molecular weight
Goods are usually used as the molecular weight polysaccharide alginate as more dispersed. Therefore, a molecular weight of sodium alginate on behalf of the group is usually the average of all molecules. The most common way to express the number molecular weight average molecular weight (Mn) and weight-average molecular weight (Mw). The two defined by the following formula:

Where Ni = Mi with a specific number of molecules of molecular weight, Wi = Mi with a specific molecular weight molecular weight.

Molecular dispersion in a multi-group, usually Mw> Mn. Mw / Mn of the coefficient of dispersion index, commodity index alginate classic range of 1.5 to 2.5. The most common way to determine molecular weight for the establishment, including determination of the viscosity and light scattering calculated on the basis of out of.
