leu·ko·tri·ene L0135675 (lo͞o′kə-trī′ēn)n. Any of several lipid compounds that contain 20 carbon atoms, are related to prostaglandins, and mediate the inflammatory response.
[leuko(cyte) + triene, a compound containing three double bonds (tri- + -ene).]leukotriene (ˌluːkəʊˈtraɪiːn) n (Biochemistry) one of a class of products of metabolic conversion of arachidonic acid; the active constituents of slow-reacting substance, responsible for bronchial constriction, contraction of smooth muscle, and inflammatory processes[C20: from leukocyte, in which they were discovered + triene from the conjugated triene unit that they contain]leu•ko•tri•ene or leu•co•tri•ene (ˌlu kəˈtraɪ in)
n. a lipid, C20H30O3, produced by white blood cells in an immune response to antigens, that contributes to allergic asthma and inflammatory reactions. [1975–80; leuko- + triene (see tri-, -ene)] leukotrieneenUK
leukotriene[‚lü·kō′trī‚ēn] (biochemistry) Any of a family of oxidized metabolites of certain polyunsaturated fatty acids, predominantly arachidonic acid, that mediate responses in allergic reactions and inflammations, produced in specific cells upon stimulation. leukotrieneenUK
leukotriene [loo″ko-tri´ēn] any of a group of compounds derived from unsaturated fatty acids, primarily arachidonic acid, that are extremely potent mediators of immediate hypersensitivity reactions and inflammation, producing smooth muscle contraction, especially bronchoconstriction, increased vascular permeability, and migration of leukocytes to areas of inflammation. Certain leukotrienes are collectively known as SRS-A (slow reacting substance of anaphylaxis), the name given to their potent bronchoconstrictor activity 30 years before their structure was elucidated; they also cause leakage of fluid and proteins from the microvasculature.leukotriene (lo͞o′kə-trī′ēn)n.
