Abstract
In papers currently being prepared for publication we report chemical studies on the polysaccharides of the New Zealand seaweeds in the family Gracilariaceae. As expected from other work (Duckworth et al, 1971; Ji et al., 1985; and references therein) the polysaccharides were based on the agar structure, with repeating units of alternating 3-linked β-D-galactose (some of which were methylated at C-6, pyruvylated at C-4,6, or even substituted in hitherto unrecorded ways, e.g., xylosylated at C-6 or C-4), and 4-linked α-L galactose units (which occur as the 3,6-anhydrogalactose, galactose, or galactose-6-sulfate).
