Metabolite Identification
Common NameNa-p-Hydroxycoumaroyltryptophan
DescriptionNa-p-Hydroxycoumaroyltryptophan belongs to the class of organic compounds known as n-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. Na-p-Hydroxycoumaroyltryptophan has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make na-p-hydroxycoumaroyltryptophan a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Na-p-Hydroxycoumaroyltryptophan.
