The chemical reactions and pathways resulting in the formation of alginic acid, a hydrophilic polysaccharide occurring in, for example, the cell walls of brown algae (brown seaweeds). 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 resulting in the formation of carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y, carried out by individual cells. The chemical reactions and pathways resulting in the formation of a macromolecule, any molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass, carried out by individual cells. The chemical reactions and pathways resulting in the formation of mannan, the main hemicellulose of soft (coniferous) wood, made up of D-mannose, D-glucose and D-galactose. The chemical reactions and pathways resulting in the formation of polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages, occurring at the level of an individual cell. 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 mannan, a group of polysaccharides containing a backbone composed of a polymer of D-mannose units. The chemical reactions and pathways involving hemicelluloses, plant cell wall polysaccharides that have a backbone of 1,4-linked beta-D-pyranosyl residues in which O4 is in the equatorial orientation. Many different hemicelluloses usually occur intermixed with each molecular type representing different degrees of polymerization and contain many different sugar monomers, which can include glucose, xylose, mannose, galactose, and arabinose. Hemicelluloses also contain most of the D-pentose sugars and occasionally small amounts of L-sugars as well. Xylose is always the sugar monomer present in the largest amount, but mannuronic acid and galacturonic acid also tend to be present. The chemical reactions and pathways resulting in the formation of galactomannan, a polysaccharide composed of D-galactosyl and D-mannosyl. The mannosyl units form the backbone structure (a linear main chain) with the D-galactosyl as single side units. The chemical reactions and pathways resulting in the formation of polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages.
