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 lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. 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 involving the O side chain of a lipopolysaccharide, which determines the antigenic specificity of the organism. It is made up of about 50 repeating units of a branched tetrasaccharide. The chemical reactions and pathways involving lipopolysaccharides, any of a group of related, structurally complex components of the outer membrane of Gram-negative bacteria. Lipopolysaccharides consist three covalently linked regions, lipid A, core oligosaccharide, and an O side chain. Lipid A is responsible for the toxicity of the lipopolysaccharide. 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 resulting in the formation of lipopolysaccharides, any of a group of related, structurally complex components of the outer membrane of Gram-negative bacteria. The chemical reactions and pathways resulting in the formation of the O side chain of a lipopolysaccharide, which determines the antigenic specificity of the organism. It is made up of about 50 repeating units of a branched tetrasaccharide. The chemical reactions and pathways resulting in the formation of polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages.
