Metabolite Identification
Common NameCarbazic acid
Descriptioncarbazic acid, also known as alpha-azaglycine or carbazate, belongs to the class of organic compounds known as hydrazinecarboxylic acids. These are organonitrogen compounds with the general formula RN(H)N(H)C(=O)OH (R = organyl). Based on a literature review very few articles have been published on carbazic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Carbazic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Carbazic acid is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
