Naturevolume 192pages10781080 (1961) | Download Citation



IN 1939 Nisizawa1 isolated a soluble laminaran from the fronds of the brown alga, Eisenia bicyclis. No further investigations, however, were made at that time, beyond observations on some of its chemical properties and behaviour towards enzymes. Recent detailed structural investigations are now reported.
