Arabinogalactan

Structural description

Green seaweeds Codium fragile and Codium vermilara biosynthesize water-soluble sulfated arabinogalactans (AG) and minor α(1-4) D-glucans and β(1-4) D-mannans. Arabinogalactan polysaccharides are composed of 3-linked β-D-galactopyranose and β-L-arabinopyranose residues; they are highly sulfated and potentially substituted with pyruvic acid ketals.

Moreover, it has been found that polysaccharide components cellulose, galactomannan and arabinogalactan-proteins (AGPs) represent about 50% of dry weight of coffee beans, from which AGPs constitute about 15%.

Activities and Uses

Arabinogalactan (AG) has a wide spectrum of possible uses. It can be employed, for example, as an adhesion-promoting agent in cardboard production, binding agent for gouache and watercolor, thickener in textile industry. AG has also been proposed for use in pharmaceutical industry as a binder in pill production, emulsifying agent for stabilizing oil emulsions (E number E409).

Arabinogalactans become important due to their prebiotic, cholesterol-lowering, emulsifying, immunomodulatory, and other properties which make from these glycoconjugates commercially important article for food and pharmaceutical industries (Capek et al. 2009. Carbohydrate Polymers).
