Common NameCandicine
DescriptionCandicine is a member of the class of compounds known as phenethylamines. Phenethylamines are compounds containing a phenethylamine moiety, which consists of a phenyl group substituted at the second position by an ethan-1-amine. Candicine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Candicine can be found in barley, which makes candicine a potential biomarker for the consumption of this food product. Candicine is a naturally occurring organic compound that is a quaternary ammonium salt with a phenethylamine skeleton. It is the N,N,N-trimethyl derivative of the well-known biogenic amine tyramine, and, being a natural product with a positively charged nitrogen atom in its molecular structure, it is classed as an alkaloid. Although it is found in a variety of plants, including barley, its properties have not been extensively studied with modern techniques. Candicine is toxic after parenteral administration, producing symptoms of neuromuscular blockade; further details are given in the "Pharmacology" section below.
