Resumen:
The room-temperature-extracted fraction from the red seaweed Kappaphycus al6arezii consists mainly of lowmolecular-weight carrageenans, with structural dispersion around a basic k-pattern. This dispersion results from: (a) low percentages of 3,6-anhydrogalactose and the presence of precursor units; (b) important quantities of 6-O-methyl b-D-galactose (4-sulfate) residues; (c) significant amounts of iota-repeating structure, and (d) small amounts of non-sulfated and disulfated b-D-galactose residues. Significant quantities of a-L-galactose units suggest the presence of agaroids, as it has been reported in several other carrageenophytes.
