What is Mimosine?

Plain description, key identifiers and synonyms

L-mimosine is an L-alpha-amino acid that is propionic acid substituted by an amino group at position 2 and a 3-hydroxy-4-oxopyridin-1(4H)-yl group at position 3 (the 2S-stereoisomer). It a non-protein plant amino acid isolated from Mimosa pudica. It has a role as an EC 1.14.18.1 (tyrosinase) inhibitor and a plant metabolite. It is a member of 4-pyridones and a non-proteinogenic L-alpha-amino acid. It is functionally related to a propionic acid. It is a conjugate acid of a L-mimosine(1-). It is a tautomer of a L-mimosine zwitterion.
