| 520 | 3 | |a The structures of the polysaccharides extracted from Griffithsia antarctica and Ceramium uncinatum, both from the family Ceramiaceae (order Ceramiales) were evaluated. Both were based on the agar structure with a high level of precursors. The polysaccharide from Griffithsia antarctica was almost completely sulfated at the 4-position, with approximately half the 4-linked units either anhydrogalactose or its precursor (in about equal amounts comparing the sugar analysis with the linkage analysis), and the other half sulfated at the 3-position and, additionally, with 2-xylosyl, 2-sulfate or 6-sulfate ester as substituents. The polysaccharide from Ceramium uncinatum was somewhat different in nature. One in four of the 3-linked units was sulfated at the 6-position, while half of the 4-linked units were in the anhydrogalactosyl form, with approximately equal amounts of galactose, galactose 6-sulfate (anhydrogalactose precursor) and galactose substituted with xylose making up the remaining 4-linked units. Both polysaccharides showed low levels of 6-O-methylgalactose and 2-O-methyl-3,6-anhydrogalactose. | |
