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. Stizolamine is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Stizolamine can be found in broad bean and peanut, which makes stizolamine a potential biomarker for the consumption of these food products.
