lip·id(lĭp′ĭd, lī′pĭd) also lip·ide (lĭp′īd′, lī′pīd′)
Any of a group of organic compounds, including the fats, oils, waxes, sterols, and triglycerides, that are insoluble in water but soluble in nonpolar organic solvents, are oily to the touch, and together with carbohydrates and proteins constitute the principal structural material of living cells.
[French lipide : Greek lipos, fat; see lipo- + French -ide, -ide.]
lipid(ˈlaɪpɪd; ˈlɪpɪd) or
(Biochemistry) biochem any of a large group of organic compounds that are esters of fatty acids (simple lipids, such as fats and waxes) or closely related substances (compound lipids, such as phospholipids): usually insoluble in water but soluble in alcohol and other organic solvents. They are important structural materials in living organisms. Former name: lipoid
[C20: from French lipide, from Greek lipos fat]
lip•id(ˈlɪp ɪd, ˈlaɪ pɪd)
also lip•ide(-aɪd, -ɪd; -paɪd, -pɪd)
any of a group of organic compounds comprising fats, waxes, and similar substances that are greasy, insoluble in water, and soluble in alcohol: one of the chief structural components of the living cell.
[< French lipide (1923) = Greek líp(os) fat + French -ide -id3]
Any of a large group of organic compounds composed of fats and fatty compounds that are oily to the touch and insoluble in water. Lipids include fatty acids, oils, waxes, sterols, and triglycerides. They are a source of stored energy and are a component of cell membranes.
