Carrageenan from the tetrasporic stage of Gigartina decipiens (Gigartinaceae, Rhodophyta).
Carbohydr Res. 1994 Jan 15; 252:171-82.CR

Abstract

The structure of the polysaccharide isolated from tetrasporophytic plants of the New Zealand red alga Gigartina decipiens has been determined by chemical and spectroscopic techniques. It is a linear polymer composed primarily of alternating 3-linked beta-D-galactopyranosyl 2-sulphate and 4-linked alpha-D-galactopyranosyl 2,6-disulphate residues. About 15% of the 3-linked residues have an additional sulphate ester group at the 6-position. Aside from this small extra sulphate substitution, the structure is that of the idealised lambda-carrageenan. Good quality solution-state 13C NMR spectra were recorded and interpreted for this carrageenan and for the carrageenans produced from it by solvolytic desulphation and alkali modification.
