Metabolite Identification
Common NameMaleamic Acid
Description557-24-4 belongs to the class of organic compounds known as straight chain fatty acids. These are fatty acids with a straight aliphatic chain. 557-24-4 is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Maleamic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Maleamic 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.
