Describe the structure of alginate

The commercially available alginates are white to cream coloured powders. 1% alginic acid solution gives a pH value of 2.9 while it is 2.3 and 7.5 for 1% solutions of propylene glycol and sodium alginate respectively. Alginic acid is essentially insoluble in cold or hot water, but it does swell quite strongly.  Alginic acid salts (K, Na, NH4+ Ca, and Na+ Ca) and propylene glycol alginates are soluble in cold or hot water and form stable solutions. The major properties of alginate include pH, solubility and viscosity.
