| General description: | Alginic acid is a high molecular weight linear polymer isolated from seaweed. It is a linear β-1→4-linked polymer of n-mannuronic and L-guluronic acid. It is an acid polysaccharide present in the extracellular matrix of brown algae. It is reported to inhibit the reverse transcriptase activity of HIV.
