The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids. The chemical reactions and pathways resulting in the formation of lipid A, the glycolipid moiety of bacterial lipopolysaccharides, consisting of six fatty acyl chains linked to two glucosamine residues. 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 substances; typically the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones. 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 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 the core region of bacterial lipopolysaccharides, which contains ten saccharide residues. The chemical reactions and pathways resulting in the formation of keto-3-deoxy-D-manno-octulosonic acid, an acidic sugar present in lipopolysaccharides of the outer membranes of some Gram-negative bacteria. 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 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 involving lipids, as carried out by individual cells. The chemical reactions and pathways resulting in the formation of polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages.
