A kinin is any of various structurally related polypeptides, such as bradykinin and kallikrein. They are members of the autacoid family.^[1]

They act locally to induce vasodilation and contraction of smooth muscle.^[2][3]

It is a component of the kinin-kallikrein system.

Their precursors are kininogen.^[4]

In botany, it refers to plant hormones which delay aging.^[5]

Aspirin inhibits the activation of kallenogen by interfering with the formation of kallikrien enzyme which is essential in the process of activation.
