Abstract

Galactan sulphates have been extracted from mechanically isolated cell walls of laboratory cultured conchocelis phases of Porphyra leucostricta and Bangia atropurpurea and their structure established by chemical methods and 13C-n.m.r. spectroscopy. The polysaccharides represent an extreme structure for porphyran-type polymers in that they consist almost entirely of 3-linked β-D-galactosyl residues alternating with 4-linked α-L-galactose-6-sulphate residues, the molar ratio of D to L units being approximately 1: 1. 13C-n.m.r. and gas-liquid and paper chromatography gave no indication of 6-O-methyl-D-galactose in these polymers. Conchocelis galactans are chemically distinct from porphyrans of generic phases of Porphyra and Bangia.
