Intrinsic factor (IF), also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells of the stomach.It is necessary for the absorption of vitamin B12 (cobalamin) later on in the small intestine. In humans, the gastric intrinsic factor protein is encoded by the GIF gene.t is necessary for the absorption of vitamin B12 (cobalamin) later on in the small intestine.

A kinin is any of various structurally related polypeptides, such as bradykinin and kallidin. They are members of the autacoid family. They act locally to induce vasodilation and contraction of smooth muscle. It is a component of the kinin-kallikrein system. Their precursors are kininogens. In botany, plant hormones cytokinins were first called kinins, but the name was changed to avoid confusion. Aspirin inhibits the activation of kallenogen by interfering with the formation of kallikrein enzyme which is essential in the process of activation. 1  Kinins. 2  Kinins at the US National Library of Medicine Medical Subject Headings (MeSH)  3 Kinin at Dorland's Medical Dictionary. 4  Online Medical Dictionary.
