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 [goid 6629] [evidence IEA]; The directed movement of chloride into, out of, within or between cells [goid 6821] [pmid 16020735] [evidence IDA]; The directed movement of lipids into, out of, within or between cells. Lipids are compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent [goid 6869] [evidence IEA]; The chemical reactions and pathways involving steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus [goid 8202] [evidence IEA]; The chemical reactions and pathways involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones. It is a component of the plasma membrane lipid bilayer and of plasma lipoproteins and can be found in all animal tissues [goid 8203] [evidence IEA]; The rupture of cell membranes and the loss of cytoplasm [goid 19835] [pmid 17192540] [evidence IDA]; The rupture of cell membranes and the loss of cytoplasm [goid 19835] [pmid 12621437] [evidence IDA]; Any process in an organism that results in the killing of cells of another organism, including in some cases the death of the other organism. Killing here refers to the induction of death in one cell by another cell, not cell-autonomous death due to internal or other environmental conditions [goid 31640] [pmid 12621437] [evidence IDA]; Any process in an organism that results in the killing of cells of another organism, including in some cases the death of the other organism. Killing here refers to the induction of death in one cell by another cell, not cell-autonomous death due to internal or other environmental conditions [goid 31640] [pmid 17192540] [evidence IDA]; The chemical reactions and pathways involving any conjugated, water-soluble protein in which the nonprotein moiety consists of a lipid or lipids [goid 42157] [evidence IEA]; Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens [goid 45087] [pmid 17192540] [evidence IDA]; The directed movement of lipids into, out of, within or between cells. Lipids are compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent [goid 6869] [evidence IEA]; The chemical reactions and pathways involving any conjugated, water-soluble protein in which the nonprotein moiety consists of a lipid or lipids [goid 42157] [evidence IEA]; The directed movement of lipids into, out of, within or between cells.
