Imidazole-based histidine compounds play a very important role in intracellular buffering. Histidine can be decarboxylated to histamine. Histamine can cause urticaria (hives) when it is produced during allergic reaction. Imidazole substituents are found in many pharmaceuticals. Visa mer Imidazole (ImH) is an organic compound with the formula C3N2H4. It is a white or colourless solid that is soluble in water, producing a mildly alkaline solution. In chemistry, it is an aromatic heterocycle, classified as a Visa mer Imidazole is a planar 5-membered ring, that exists in two equivalent tautomeric forms because hydrogen can be bound to one or another Visa mer Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole Visa mer Imidazole and its derivatives have high affinity for metal cations. One of the applications of imidazole is in the purification of His-tagged proteins in immobilised metal affinity chromatography (IMAC). Imidazole is used to elute tagged proteins bound to Visa mer Imidazole was first reported in 1858 by the German chemist Heinrich Debus, although various imidazole derivatives had been discovered as early as the 1840s. It was shown that glyoxal, formaldehyde, and ammonia condense to form imidazole (glyoxaline, as it … Visa mer Imidazole itself has few direct applications.
