Water-soluble Polysaccharides of Porphyra Species : a Note on the Classification of P. naiadum

Nature volume 195, pages 398–399 (1962)Cite this article

Abstract

THE water-soluble mucilages which are present in copious amounts in the red seaweeds (Rhodophyta) are usually sulphated polysaccharides containing galactose, 3,6-anhydrogalactose and, more rarely, 6-O-methylgalactose units. These polysaccharides are by no means identical in all red seaweeds, and it has been suggested1 that the composition of the mucilage might provide a useful additional criterion in classification within the group. We have now isolated and analysed the water-soluble polysaccharides from some fifty different collections of the genus Porphyra, and this communication reports the bearing of our results on the classification of the alga hitherto known as P. naiadum And.
