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]; Any process of the innate immune response that takes place in the mucosal tissues [goid 2227] [pmid 15254593] [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]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lipid hydroperoxide stimulus. Lipid hydroperoxide is the highly reactive primary oxygenated products of polyunsaturated fatty acids [goid 6982] [pmid 16945374] [evidence IDA]; The attachment of a leukocyte to another cell via adhesion molecules [goid 7159] [pmid 15254593] [evidence IDA]; 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] [pmid 1935934] [evidence IDA]; Any process involved in removing superoxide radicals (O2-) from a cell or organism, e.g. by conversion to dioxygen (O2) and hydrogen peroxide (H2O2) [goid 19430] [pmid 16945374] [evidence IDA]; Any process that modulates the frequency, rate or extent of the directed movement of cholesterol into, out of, within or between cells [goid 32374] [pmid 11940599] [evidence IDA]; The directed movement of cholesterol, cholest-5-en-3-beta-ol, out of a cell or organelle [goid 33344] [pmid 11162594] [evidence IDA]; The directed movement of cholesterol, cholest-5-en-3-beta-ol, out of a cell or organelle [goid 33344] [pmid 1935934] [evidence IDA]; The directed movement of a phospholipid out of a cell or organelle [goid 33700] [pmid 11162594] [evidence IDA]; Any process that stops, prevents, or reduces the frequency, rate or extent of lipoprotein oxidation, occurring in the blood plasma [goid 34445] [pmid 16945374] [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]; Any process involved in the maintenance of an internal equilibrium of cholesterol within an organism or cell [goid 42632] [pmid 1935934] [evidence IDA]; The chemical reactions and pathways resulting in the breakdown of hydrogen peroxide (H2O2) [goid 42744] [pmid 16945374] [evidence IDA]; The directed movement of periperal cell cholesterol, cholest-5-en-3-beta-ol, towards the liver for catabolism [goid 43691] [pmid 3095477] [evidence IDA]; The chemical reactions and pathways resulting in the breakdown of lipids, occurring at the tissue, organ, or organismal level of a multicellular organism [goid 44240] [pmid 3095477] [evidence IDA]; The chemical reactions and pathways involving phosphatidylcholines, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of choline. They are important constituents of cell membranes [goid 46470] [pmid 1935934] [evidence IDA]; Any process involved in the maintenance of an internal equilibrium of lipid within an organism or cell [goid 55088] [pmid 3095477] [evidence IDA]; The aggregation, arrangement and bonding together of proteins and lipids to form a protein-lipid complex [goid 65005] [pmid 16159879] [evidence IMP]
