Chemical Information
FooDB NamePropylpyrazine
DescriptionPropylpyrazine 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. Propylpyrazine is a green, nutty, and vegetable tasting compound. Propylpyrazine 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 propylpyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Propylpyrazine.
