WebA kinin is any of various structurally related polypeptides, such as bradykinin and kallidin. They are members of the autacoid family. Kinins are peptides that are cleaved from kininogens by the process of kallikreins. Kallikreins activate kinins when stimulated. It is a component of the kinin-kallikrein system. Their precursors are kininogens. WebDec 17, 2024 · Kallidin (KD) has the same amino acid sequence as Bradykinin with the addition of a Lysine at the N-terminus, thus it is also called Lys-BK. Kallidin is released from LK by tissue kallikrein. Kinins are potent hypotensive peptide hormones that are also involved in pain, neurotransmission, inflammation and cell proliferation processes.
