Chemical Information
FooDB NamePyridine
DescriptionPyridine, also known as azabenzene or py, belongs to the class of organic compounds known as pyridines and derivatives. Pyridines and derivatives are compounds containing a pyridine ring, which is a six-member aromatic heterocycle which consists of one nitrogen atom and five carbon atoms. Pyridine exists in all living organisms, ranging from bacteria to humans. Pyridine is an amine, fishy, and putrid tasting compound. Pyridine is found, on average, in the highest concentration within kohlrabis (Brassica oleracea var. gongylodes) and peppermints (Mentha X piperita). Pyridine has also been detected, but not quantified in, several different foods, such as celeriacs (Apium graveolens var. rapaceum), tortilla chip, red bell peppers (Capsicum annuum), soy beans (Glycine max), and corns (Zea mays). This could make pyridine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Pyridine.
