DescriptionImidazole acetol-phosphate belongs to the class of organic compounds known as monoalkyl phosphates. These are organic compounds containing a phosphate group that is linked to exactly one alkyl chain. Imidazole acetol-phosphate is a very strong basic compound (based on its pKa). Imidazole acetol-phosphate exists in all living species, ranging from bacteria to humans. Within yeast, imidazole acetol-phosphate participates in a number of enzymatic reactions. In particular, imidazole acetol-phosphate can be biosynthesized from D-erythro-imidazole-glycerol-phosphate through the action of the enzyme imidazole glycerol-phosphate dehydratase. In addition, imidazole acetol-phosphate and L-glutamic acid can be converted into oxoglutaric acid and L-histidinol phosphate; which is mediated by the enzyme histidinol-phosphate aminotransferase. In yeast, imidazole acetol-phosphate is involved in the metabolic pathway called histidine biosynthesis pathway.
