High-field NMR spectroscopy of cystocarpic and tetrasporic carrageenans from Iridaea undulosa

High-field 1H and 13C NMR spectroscopy has been used to characterize the fine structure of the cystocarpic and tetrasporic carrageenans from Iridaea undulosa. The proportion of different carrageenans from the κ-family in cystocarpic samples were calculated. In the 13C NMR spectra of the tetrasporic...
