Chemical Information
FooDB Name4-Phenylpyridine
Description4-Phenylpyridine belongs to the class of organic compounds known as phenylpyridines. These are polycyclic aromatic compounds containing a benzene ring linked to a pyridine ring through a CC or CN bond. 4-Phenylpyridine has been detected, but not quantified in, several different foods, such as herbal tea, herbs and spices, black tea, sweet oranges (Citrus sinensis), and red tea. This could make 4-phenylpyridine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 4-Phenylpyridine.
