Chemical Information
FooDB Name5H-Cyclopentapyrazine
Description5H-Cyclopentapyrazine 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. 5H-Cyclopentapyrazine has been detected, but not quantified in, pulses. This could make 5H-cyclopentapyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 5H-Cyclopentapyrazine.
