Histidine decarboxylation - Big Chemical Encyclopedia

Histidine - Decarboxylation of histidine yields histamine (see here). In the stomach, histamine promotes secretion of hydrochloric acid and pepsin as digestion aids. Histamine is a potent vasodilator, released at sites of trauma, inflammation, or allergic reaction. Reddening of inflamed tissues is a result of local enlargement of blood capillaries.

Histidine Decarboxylase - an overview | ScienceDirect Topics

Histamine is formed by decarboxylation of histidine alyzed by histidine decarboxylase. It is stored preformed in cytoplasmic granules of mast cells and basophils, and within platelets of some species. Synthesis occurs also in other cells within the gastric mucosa, nervous tissue, and lymphatics. A variety of stimuli induce histamine release.
