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 breakdown of membrane lipids, any lipid found in or associated with a biological membrane. The chemical reactions and pathways resulting in the breakdown of lipids, as carried out by individual cells. The chemical reactions and pathways resulting in the breakdown of any isoprenoid compound, isoprene (2-methylbuta-1,3-diene) or compounds containing or derived from linked isoprene (3-methyl-2-butenylene) residues. The chemical reactions and pathways resulting in the breakdown of substances, including the breakdown of carbon compounds with the liberation of energy for use by the cell or organism. The chemical reactions and pathways resulting in the breakdown of a fatty acid, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils. Fatty acids are predominantly straight-chain acids of 4 to 24 carbon atoms, which may be saturated or unsaturated; branched fatty acids and hydroxy fatty acids also occur, and very long chain acids of over 30 carbons are found in waxes. The chemical reactions and pathways resulting in the breakdown of lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. The chemical reactions and pathways resulting in the breakdown of neutral lipids, lipids only soluble in solvents of very low polarity. The chemical reactions and pathways resulting in the breakdown of substances, carried out by individual cells. The chemical reactions and pathways resulting in the breakdown of phospholipids, any lipid containing phosphoric acid as a mono- or diester. The chemical reactions and pathways resulting in the breakdown of glycerolipids, any lipid with a glycerol backbone. The chemical reactions and pathways by which individual cells transform chemical substances. The chemical reactions and pathways involving lipids, as carried out by individual cells. The chemical reactions and pathways resulting in the breakdown of lipopolysaccharides, any of a group of related, structurally complex components of the outer membrane of Gram-negative bacteria.
