2-Aminomuconic semialdehyde is a metabolite of tryptophan which is an unstable open-chain biochemical precursor of picolinic acid.[1][2][3]

Biochemistry

[edit]

2-Aminomuconic semialdehyde is an intermediate in the kynurenine pathway of tryptophan metabolism, which leads to picolinic acid or quinolinic acid. The enzyme aminocarboxymuconate-semialdehyde decarboxylase produces it from 2-amino-3-carboxymuconic semialdehyde, a compound which would form quinolinic acid in the absence of that enzyme.[3]

2-Aminomuconic semialdehyde itself is chemically unstable and spontaneously ring-closes to picolinic acid, with loss of water.[3][4]
