Metabolite Identification
Common NameNb-Palmitoyltryptamine
DescriptionNb-Palmitoyltryptamine belongs to the class of organic compounds known as 3-alkylindoles. 3-alkylindoles are compounds containing an indole moiety that carries an alkyl chain at the 3-position. Nb-Palmitoyltryptamine has been detected, but not quantified in, alcoholic beverages and fruits. This could make NB-palmitoyltryptamine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Nb-Palmitoyltryptamine.
