bradykinin /brady·ki·nin/ (-ki´nin) a nonapeptide kinin formed from HMW kininogen by the action of kallikrein; it is a very powerful vasodilator and increases capillary permeability; in addition, it constricts smooth muscle and stimulates pain receptors.
bradykinin
bradykinin (brā´d
kī´nin),
brad·y·ki·nin (br d  -k  nn, -knn)n. A biologically active polypeptide that forms from a blood plasma globulin and mediates the inflammatory response, increases vasodilation, and causes contraction of smooth muscle. Also called kallidin I. |
bradykinin
[-kī′nin]
Etymology: Gk, bradys + kinein, to move
a peptide containing nine amino acid residues produced from α2-globulin by the enzyme kallikrein. Bradykinin is a potent vasodilator.
bradykinin (brā´d
kī´nin),n one of a number of plasma kinins, a potent vasodilator; physiologic mediators of an anaphylactic reaction.
bradykinin
a nonapeptide kinin formed from a plasma protein, high-molecular-weight (HMW) kininogen, by the action of kallikrein; it is a very powerful vasodilator that increases capillary permeability and, in addition, constricts smooth muscle and stimulates pain receptors.
