IR studies on carrageenan of Ahnfeltia concinna, a marine red alga.
The principal polysaccharide of Ahnfeltia concinna gave IR absorptions at 1240, 930, 845-850, and 805 cm-1, all typical of a carrageenan. The polysaccharide was separated into soluble and insoluble fractions with potassium chloride.
