Alginic add

This is composed of the sodium and ealeium salts of alginic add formed into a powder or fibrous material and sterilized by autoelaving. It aids clotting by forming a sodium-caldum alginate complex in contact with tissue fluids, acting principally as a mechanical haemostat. It is relatively slowly absorbed and some residues may occasionally remain in the tissues.

Demulcents are agents or preparations that protect the mucous membranes and relieve pain and irritation. They are thought to work by forming a protective film and are commonly incorporated into antacid preparations for protecting the gastric mucosa of the mouth. The most commonly used is alginic add or one of its alginate salts.

Chapter 9. A substrate used in the assay of L-iduronic acid 2-sulphate sulphatase was obtained from sodium heparinate by methanolysis followed by nitrosation. Disaccharide monosulphates presumed to contain D-(methyl a-L-idopyranosiduronate-2-sulphate)-(l 4)-2,5-anhydro-D-mannose were isolated by gel filtration. Brucine L-guluronate and o-mannuronate, on the other hand, were obtained by treatment with brucine of the barium salts of the acids formed on hydrolysis of alginic add. ... 

Alginic acid is a white or somewhat off-white powder only slightly soluble in boiling water. The alkali metal salts of alginic add are water-soluble and form at low concentrations highly viscous solutions. When dried, alginic acid solutions become hard, homy, and resistant to solvents. Alginic acid is a weak acid, and forms many derivatives of unusual and useful properties .
