Resumen:
Several points concerning the presence in red seaweeds of galactans with cooccurrence of carrageenan and agaran structures (DL-hybrid galactans) are addressed:
a. Analysis of D- and L-galactose enantiomers and their methylated and cyclic derivatives. Spectroscopic, enzymatic and chemical methodologies.
b. Systems of galactans, in which the presence of D- and L-galactose has been determined (DL-galactan systems).
c. The possible deviant structures of carrageenans and agarans in DL-hybrid galactans.
d. The isolation of pure carrageenans and agarans from DL-galactan systems.
e. The formation of molecular complexes between carrageenans, agarans and carrageenan/agarans.
f. DL-hybrid galactans or molecular complexes: Evidences in favor of each hypothesis.
