Metabolite Identification
Common Namealpha-Allocryptopine
DescriptionAlpha-allocryptopine, also known as alpha-fagarine or beta-homochelidonine, is a member of the class of compounds known as protopine alkaloids. Protopine alkaloids are alkaloids with a structure based on a tricyclic protopine formed by oxidative ring fission of protoberberine N-metho salts. Alpha-allocryptopine is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Alpha-allocryptopine can be found in barley, which makes alpha-allocryptopine a potential biomarker for the consumption of this food product.
