low-molecular-weight carrageenan oligosaccharides are obtained. Antitumor activities of the oligosaccharides are tested on Sarcoma 180 tumor transplanted in mice. The carrageenan oligosaccharide show much higher tumor inhibition (70.8%) and catalase activity at a dosage of 100 mg/kg compared with the control group

-
the average molecular mass of solid carrageenan decreases very slowly, and tetrasaccharide production is high. kappa-carrageenase is a processive enzyme when acting on solid substrates. It has a random mode of action on soluble substrates. The conditions for processivity not only require that the active site possesses the adapted topology, but also that the substrate is in an appropriate physical and conformational state (processivity is similar for gel and powder)

hybrid kappa/iota-carrageeans extracted from Gigartina skottsbergii, Chondracanthus chamissoi, and Chondrus crispus are incubated with kappa-carrageenase. The degradation products of the kappa-carrageenase allow discriminating three modes of kappa-carrabiose distribution: blocks of kappa-carrabiose, kappa-carrabiose rich fraction containing iota-carrabiose units probably randomly distributed, and iota-carrabiose rich fraction which corresponds to the resistant fraction
