The fraction of the carrageenans from the tetrasporic stage of Iridaea undulosa soluble in potassium chloride was subfractionated by ion-exchange chromatography on an anion exchanger diluted with gel permeation media. The system under analysis consists of a mixture of lambda-carrageenans and variant agaroids. The latter contain large amounts of 3-linked 6-substituted units and galactose side chains. In some molecules, D-glucose units replace D-galactose ones.
