“…Red algae of the order Gigartinales belonging to the families Phyllophoraceae, Gigartinaceae or Soleriaceae have been reported to synthetize iota-carrageenan (Mollion 1980, Bellion et al 1981, 1983, Chopin et al 1991. Carrageenans are cell wall sulfated polysaccharides of alternative α (1 -* 3) and β (1 -* 4) linked D-galactopyranose residues, the repeating neocarrabiose unit of iota-carrageenan consisting of galactose-4-sulfate (G4) and 3,6-anhydrogalactose-2-sulfate (AG 2) (Fig.…”

The chemical composition of the phycocollbids from two Senegalese red algae Anatheca montagnei and Meristotheca senegalensis (Soleriaceae) has been compared with the hybrid iota-kappa carrageenan from commercial Euchema spinosum.. A. partially desulfated major iota carrageenan was identified. The milk strengths of gels from the Senegalese species were similar to those from Euchema spinosum suggesting potential economical applications.

“…Pure K. and L-carrageenans may exist, but most of the carrageenans we have seen are mixtures of the two, or K-t hybrids . Evidence for the latter interpretation, that both units exist in the same molecule, has been presented by Bellion, et al (1980) .…”

“…The agar extracted from E112 (Pterocladia capillacea), I although crude, has a spectrum that shows virtually no substitution . The gel state spectrum of ic-carrageenan shows the typical dominant peaks at 102 .3 and 95.1 ppm in the anomeric region, but there is a distinct minor peak at 62 .1 ppm due to an iota moiety within the kappa molecules (Bellion et al, 1981).…”

Both solid state (CP-MAS) and gel state (using standard solution state conditions) 13 C NMR spectroscopy have been used to characterize a range of red algae that produce either agar or carrageenan . These techniques allow rapid determination of phycocolloid type within the algal tissue before extensive and time-consuming extractions and fractionations are carried out .The gel state technique can be used on living or dried material . Gel state spectra give high resolution and, because of the expectation that they will be correlated with the extractable phycocolloid, provide promise of a powerful technique for screening potentially useful red algae .
