Definition
Imidazole-4-acetaldehyde is a naturally occurring aldehyde metabolite of histamine formed by the action of histaminase (E.C. 1.4.3.6), and can be synthesized by oxidation of histidine. Aldehyde dehydrogenase (EC 1.2.1.3) is the only enzyme in the human liver capable of catalyzing dehydrogenation of aldehydes arising via monoamine, diamine, and plasma amine oxidases. NAD-linked dehydrogenation of short chain aliphatic aldehydes has been found in virtually every organ of the mammalian body. Imidazole-4-acetaldehyde is a good substrate for all aldehyde dehydrogenase isozymes. Experimentally, the prebiotic formation of histidine has been accomplished by the reaction of erythrose with formamidine followed by a Strecker synthesis. Imidazole-4-acetaldehyde could have been converted to histidine on the primitive earth by a Strecker synthesis, and several prebiotic reactions could convert imidazole-4-glycol and imidazole-4-ethanol to imidazole-4-acetaldehyde. (PMID: 2071588 , 2957640 , 11536478 ).
Belongs to the class of organic compounds known as imidazoles. Imidazoles are compounds containing an imidazole ring, which is an aromatic five-member ring with two nitrogen atoms at positions 1 and 3, and three carbon atoms.
