The carrageenans produced by the cystocarpic and tetrasporic stages from Iridaea undulosa were fractionated by potassium chloride precipitation and analyzed. The cystocarpic system is composed of similar amounts of a gelling carrageenan with ~/~-characteristics, and a soluble, partially cyclized, p

✦ Synopsis
The combined use of methylation analysis and high-field 1H and 13C NMR spectroscopy allows the determination of the fine structure of the carrageenans produced by the cystocarpic stage of Gigartina skottsbergii.
