Metabolite Identification
Common NameLidofenin
DescriptionLidofenin, also known as gadolinium-hida or hepato-scan, belongs to the class of organic compounds known as alpha amino acid amides. These are amide derivatives of alpha amino acids. Lidofenin is a moderately basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Lidofenin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lidofenin 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.
