Structure of the 'corallinans' - sulfated xylogalactans from Corallina officinalis
The structure of the main polysaccharides extracted from the red seaweed Corallina officinalis was characterized by methylation, desulfation-methylation, and ethylation analysis. The backbone has an alternating →4)-α-l-Gal-(1 →3)-β-d-Gal-(1 → structure. The C6 position of 3-linked units is substitut...
