Metabolite Identification
Common NameNalpha-Cinnamoylhistamine
Descriptioncinnamoylhistamine belongs to the class of organic compounds known as cinnamic acid amides. These are amides of cinnamic acids. Cinnamic acid is an aromatic compound containing a benzene and a carboxylic acid group forming 3-phenylprop-2-enoic acid. cinnamoylhistamine is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Nalpha-cinnamoylhistamine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nalpha-Cinnamoylhistamine 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.
