Plants catalyze the biosynthesis of a large number of non-protein amino acids, which are usually toxic for other organisms. In this review, the chemistry and metabolism of N-heterocyclic non-protein amino acids from plants are described. These N-heterocyclic non-protein amino acids are composed of β-substituted alanines and include mimosine, β-pyrazol-1-yl-L-alanine, willardiine, isowillardiine, and lathyrine. These β-substituted alanines consisted of an N-heterocyclic moiety and an alanyl side chain. This review explains how these i
