Resumen
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 B-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 B-D-galactose or O-4 and O-6 of 3-linked B-D-galactose. ii) Sulfated 3-linked B-L-arabinans substituted on C-2 or C-2 and C-4 predominantly with sulfate, but also with single stubs of arabinose, and iii) 4-Linked B-D-mannans with a low degree of sulfation 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 two similar fibrillar layers separated by a zone rich in charged polymers. Besides, arabinogalactan proteins co-localized with the fibrillar components.
