Polysaccharides from the green seaweed Codium decorticatum. Structure and cell wall distribution

The cell wall polysaccharides from Codium decorticatum and their assembly were studied and these results were compared with those obtained previously for this genus. The water soluble polysaccharides are:(i) Pyruvylated and sulfated 3- and 6-linked -d–galactans with sulfate mainly on C-4 and also on C-6.Pyruvate ketals are linked to O-3 and O-4 of terminal -d galactose or O-4 and O-6 of 3-linked -d-galactose. (ii) Sulfated 3-linked -l-arabinans substituted on C-2 or C-2 and C-4 predominantly withsulfate, but also with single stubs of arabinose, and (iii) 4-linked -d-mannans with a low degree ofsulfation on C-2. The whole polysaccharide system comprises 6.9% of sulfated polysaccharides and 32.9%of fibrillar polysaccharides, mostly insoluble mannans. By in situ localization it was possible to detect twosimilar fibrillar layers separated by a zone rich in charged polymers. Besides, arabinogalactan proteinsco-localized with the fibrillar components.
