The chemical reactions and pathways involving polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages, as carried out by individual cells. The chemical reactions and pathways involving macromolecules forming, or destined to form, part of a cell wall. A cell wall is a rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis, occurring at the level of the cell. The chemical reactions and pathways involving rhamnogalacturonan I (RGI), a branched pectin with a backbone of alternating alpha-(1->2)-linked rhamnose and alpha-(1->4)-linked D-galacturonic acid residues that carries neutral side-chains of predominantly beta-(1->4)-D-galactose and/or alpha-(1->5)-L-arabinose residues attached to the rhamnose residues of the RGI backbone. The chemical reactions and pathways involving the side chains of the pectin, rhamnogalacturonan I. The chemical reactions and pathways involving galactan, a polymer of D-galactosyl units that can be found as a side chain of the pectin rhamnogalacturonan I. The chemical reactions and pathways involving pectin, a polymer containing a backbone of alpha-1,4-linked D-galacturonic acid residues, as part of the organization and biogenesis of the cell wall. The chemical reactions and pathways involving arabinan, a polymer with an alpha-(1->5)-linked -L-arabinofuranose (Araf) backbone that can be substituted with Araf-alpha-(1->2)-, Araf-alpha-(1->3)-, and/or Araf-alpha-(1->3)-Araf-alpha-(1->3)-side chains. Arabinan can be found as a side chain of the pectin rhamnogalacturonan I. The chemical reactions and pathways involving pectic arabinogalactan I, an alpha-(1->4)-linked D-galactopyranose backbone that is substituted with alpha-l-Araf residues via the O-3 of the D-galactose residues. Arabinogalactan I can be found as a side chain of rhamnogalacturonan I.
