Metabolite Identification

Common Name

2-Methyl-5-(1-propenyl)pyrazine

Description

2-Methyl-5-(1-propenyl)pyrazine belongs to the class of organic compounds known as pyrazines. Pyrazines are compounds containing a pyrazine ring, which is a six-member aromatic heterocycle, that consists of two nitrogen atoms (at positions 1 and 4) and four carbon atoms. 2-Methyl-5-(1-propenyl)pyrazine has been detected, but not quantified in, several different foods, such as green vegetables, arabica coffees (Coffea arabica), green tea, coffee and coffee products, and teas (Camellia sinensis). This could make 2-methyl-5-(1-propenyl)pyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methyl-5-(1-propenyl)pyrazine.
