Room temperature, low-field 13C-n.m.r. spectra of degraded carrageenans. Part II. On the specificity of the autohydrolysis reaction in kappa/iota and mu/nu structures

A kappa/iota carrageenan from Gigartina skottsbergii and a partially cyclized mu/nu carrageenan from Iridaea undulosa were submitted to autohydrolysis. The 13C-n.m.r. spectra of the degraded products give structural information on the polysaccharides and show clearly that besides the known splitting...
