title: Room temperature, low-field 13C-n.m.r. spectra of degraded carrageenans: Part III. Autohydrolysis of a lambda carrageenan and of its alkali-treated derivative.
abstract: Autohydrolysis of lambda and theta carrageenans produces degraded products which are useful for 13C-n.m.r. spectroscopy, with low-field equipment and at room temperature. Data obtained from these spectra are doubly valuable as they are used for the structural study of parent carrageenans and to investigate the reactions carried out during autohydrolysis.
