Alkaline treatment of the carrageenans from the cystocarpic stage of the red seaweed Iridaea undulosa

The carrageenans from the cystocarpic stage from the red seaweed Iridaea undulosa were fractionated by means of potassium chloride precipitation. The soluble and insoluble fractions were treated with alkali. The products were refractionated with potassium chloride, giving rise to several fractions,...
