Chemical Properties:
  1. Alginic acid found in the walls of brown seaweeds (Phaeophyceae) consists of D-mannuronic acid  units and L-guluronic acid units probably linked β (1->4). The chains contain three distinct regions; in one, the D-mannuronic acid units alternate with L-guluronic acid units, whereas the remaining regions are homogeneous and contain either D-mannuronic acid or L-guluronic acid. The lengths and proportions of the three regions vary with the seaweed species and are responsible for the differences in chemical and physical properties of the various alginates.
  2. Alginic acid is biosynthesised from GDP-D-mannuronic acid and GDP-guluronic acid. It seems probable that guluronic acid is derived from its isomer, mannuronic acid, the re action being catalysed by an epimerase.
  3. Alginic acid  monovalent salts of alginic acid are soluble in water, but polyvalent salts are either insoluble or form gels. Solutions of alginates are very viscous due to the high molecular weight and random-coil formation of the polymers. The jellying and thickening properties of alginates are widely used commercially in foodstuffs, etc.
  1. Alginic acid  gum derived from alginic acid which is obtained from brown seaweed genera, such as Macrocystis pyrifera. The derivatives are sodium, ammonium, and potassium ates of which the sodium salt is most common. They are used to provide thickening, gelling, and binding. A derivative designed for improved acid and calcium stability is propylene glycol ate. The s are soluble in cold water and form nonthermoreversible gels in reaction with calcium ions and under acidic conditions. Algin is used in ice cream, icings, puddings, dessert gels, and fabricated fruit.
  2. Alginic acid is used in cosmetic formulations as a thickener, stabilizer, and gelling agent. It is obtained from different varieties of brown seaweed.
  3. Alginic Acid is the acidic, insoluble form of algin that is a white to yellowish fibrous powder obtained from brown seaweed genera, such as macrocystis pyrifera. the derivatives are soluble and include sodium, potassium, and ammonium alginate and propylene glycol alginate. it is used as a tablet disintegrant and as an antacid ingredient.
