The carrageenans of gigartina skottsbergii s. et g. Part III. methylation analysis of the fraction precipitated with 0.3-0.4m potassium chloride

The fraction of carrageenan from the red seaweed Gigartina skottsbergii that is precipitated with 0.3-0.4m potassium chloride has been studied by methylation analysis. The results agree qualitatively with the structure previously suggested, except that 3-linked D-galactose 4-sulfate residues are pre...

The results agree qualitatively with the structure previously suggested, except that 3-linked D-galactose 4-sulfate residues are present rather than the corresponding 2-sulfate. For every ten D-galactose residues linked at C-3, there are, on the average, six residues of 3,6-anhydro-D-galactose linked at C-4 and ten sulfate groups (five as 3,6-anhydro-D-galactose 2-sulfate and five as D-galactose 4-sulfate residues). © 1973.
