A kinin is any of various structurally related polypeptides , such as bradykinin and kallidin .[ 1] They are members of the autacoid family.[ 2] Kinins are peptides that are cleaved from kininogens by the process of kallikreins. Kallikreins activate kinins when stimulated.[ 3]
It is a component of the kinin-kallikrein system .
Their precursors are kininogens .[ 4] Kininogens contain a 9-11 amino acid bradykinin sequence.[ 5]
In botany , the plant hormones known as cytokinins were first called kinins, but the name was changed to avoid confusion.[ 6]
